Modern flexcan IP cores support two RX modes. One is using the 6 fames deep
hardware FIFO, the other is using up to 64 mailboxes (in non FIFO mode). For
now only the HW FIFO mode is activated.
In order to make use of the RX mailboxes the individual RX masking feature has
to be activated, otherwise matching mailboxes are overwritten during the
reception process. This however switches on the individual RX masking, which
uses reg_rximr registers for masking.
This patch activates the individual RX masking feature unconditionally and
initializes the mask registers (reg_rximr) with 0x0 == "don't care", which
switches off any filtering.

This patch converts the flexcan driver to make use of the rx-offload
can_rx_offload_irq_offload_fifo() helper function. The idea is to read
the CAN frames already in the interrupt context, as the depth of the
flexcan HW FIFO is too shallow, resulting in too many missed frames.
During a normal NAPI poll the frames are the pushed into the upper
layers.

Some CAN controllers don't implement a FIFO in hardware, but fill their
mailboxes in a particular order (from lowest to highest or highest to lowest).
This makes problems to read the frames in the correct order from the hardware,
as new frames might be filled into just read (low) mailboxes. This gets worse,
when following new frames are received into not read (higher) mailboxes.
On the bright side some these CAN controllers put a timestamp on each received
CAN frame. This patch adds support to offload CAN frames in interrupt context,
order them by timestamp and then transmitted in a NAPI context.

====================
net: ipv6: Improve user experience with multipath routes
This series closes a couple of gaps between IPv4 and IPv6 with respect
to multipath routes:
1. IPv4 allows all nexthops of multipath routes to be deleted using just
the prefix and length; IPv6 only deletes the first nexthop for the
route if only the prefix and length are given.
2. IPv4 returns multipath routes encoded in the RTA_MULTIPATH attribute.
IPv6 returns a series of routes with the same prefix and length - one
for each nexthop. This happens for both dumps and notifications.
IPv6 does accept RTA_MULTIPATH encoded routes, but installs them as a
series of routes.
Patch 1 addresses the first item by allowing IPv6 multipath routes to be
deleted using just the prefix and length. Patch 2 addresses the second
allowing IPv6 multipath routes to be returned encoded in the RTA_MULTIPATH.
Patches 3 and 4 upate the RTM_{NEW,DEL}ROUTE notifications to generate
1 notification with RTA_MULTIPATH where applicable.
Patch 5 prints IPv6 addresses in compressed format when showing route
replace errors. This was noticed testing REPLACE failures.
The end result for multipath routes:
1. Dump
- RTA_MULTIPATH used for multipath routes
$ ip -6 ro ls vrf red
2001:db8:1::/120 dev eth1 proto kernel metric 256 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium
2001:db8:200::/120 metric 1024
nexthop via 2001:db8:1::2 dev eth1 weight 1
nexthop via 2001:db8:2::2 dev eth2 weight 1
...
2. Route Add
- one notification with RTA_MULTIPATH attribute
$ ip -6 ro add vrf red 2001:db8:200::/120 nexthop via 2001:db8:1::2 nexthop via 2001:db8:2::2
$ ip mon route
2001:db8:200::/120 table red metric 1024
nexthop via 2001:db8:1::2 dev eth1 weight 1
nexthop via 2001:db8:2::2 dev eth2 weight 1
2. Route Replace
- one notification with RTA_MULTIPATH attribute
$ ip -6 ro replace vrf red 2001:db8:200::/120 nexthop via 2001:db8:1::16 nexthop via 2001:db8:2::16
$ ip mon route
Replaced 2001:db8:200::/120 table red metric 1024
nexthop via 2001:db8:1::16 dev eth1 weight 1
nexthop via 2001:db8:2::16 dev eth2 weight 1
- on a failure after the insertion of the first nexthop (which means
the original route has been replaced in the FIB), a notification is
sent with the successful nexthops and then the nexthops are deleted
with one notification per hop. This is consistent with how it works
today except the successful additions are coalesced into 1
notification.
3. Route Delete
- delete of entire multipath route using prefix/length only 1
notification is generated:
$ ip -6 ro del vrf red 2001:db8:200::/120
$ ip mon route
Deleted 2001:db8:200::/120 table red metric 1024
nexthop via 2001:db8:1::16 dev eth1 weight 1
nexthop via 2001:db8:2::16 dev eth2 weight 1
- if a delete request contains nexthops one notification is
generated per nexthop deleted. This is unavoidable since IPv6
alllows a single nexthop to be deleted within a multipath route
4. Route Appends
- IPv6 allows nexthops to be appended to an existing route. In this
case one notification is sent for the new route with the append
flag set.
$ ip -6 ro append vrf red 2001:db8:200::/120 nexthop via 2001:db8:2::20 nexthop via 2001:db8:1::20
$ ip mon route
Append 2001:db8:200::/120 table red metric 1024
nexthop via 2001:db8:1::2 dev eth1 weight 1
nexthop via 2001:db8:2::2 dev eth2 weight 1
nexthop via 2001:db8:2::20 dev eth2 weight 1
nexthop via 2001:db8:1::20 dev eth1 weight 1
- on failure of an append, a notification is sent with the route
containing all of the nexthops successfully added, and it is
followed by delete notifications as the hops are removed
returning the route to its prior state. This is consistent with
how it works today except the successful additions are coalesced
into 1 notification.
Addresses some of the inconsistencies also noted by Roopa at netdev0.1:
https://www.netdev01.org/docs/prabhu-linux_ipv4_ipv6_inconsistencies_talk_slides.pdf
v4
- changed series to do encoding in 1 patch and updating notificatons
in separate patches to make it easier to review and understand
- 1 notification for delete when using prefix/length; 1 notification for
append
- handle delete of a single nexthop without RTA_MULTIPATH in delete request
- upated commit messages and cover letter
v3
- removed the need for a user API to opt-in to change. Requiring an
API just shifts the difference from same API with different
behavior to different API to achieve equivalent behavior
- route notifications changed to use RTA_MULTIPATH for add and replace
- upated commit messages and cover letter
v2
- fixed locking in patch 1 as noted by DaveM
- changed user API for patch 2 to require an rtmsg with RTM_F_ALL_NEXTHOPS
set in rtm_flags
- revamped explanation of patch 2 and cover letter

If an entire multipath route is deleted using prefix and len (without any
nexthops), send a single RTM_DELROUTE notification with the full route
using RTA_MULTIPATH. This is done by generating the skb before the route
delete when all of the sibling routes are still present but sending it
after the route has been removed from the FIB. The skip_notify flag
is used to tell the lower fib code not to send notifications for the
individual nexthop routes.
If a route is deleted using RTA_MULTIPATH for any nexthops or a single
nexthop entry is deleted, then the nexthops are deleted one at a time with
notifications sent as each hop is deleted. This is necessary given that
IPv6 allows individual hops within a route to be deleted.

Change ip6_route_multipath_add to send one notifciation with the full
route encoded with RTA_MULTIPATH instead of a series of individual routes.
This is done by adding a skip_notify flag to the nl_info struct. The
flag is used to skip sending of the notification in the fib code that
actually inserts the route. Once the full route has been added, a
notification is generated with all nexthops.
ip6_route_multipath_add handles 3 use cases: new routes, route replace,
and route append. The multipath notification generated needs to be
consistent with the order of the nexthops and it should be consistent
with the order in a FIB dump which means the route with the first nexthop
needs to be used as the route reference. For the first 2 cases (new and
replace), a reference to the route used to send the notification is
obtained by saving the first route added. For the append case, the last
route added is used to loop back to its first sibling route which is
the first nexthop in the multipath route.

IPv6 returns multipath routes as a series of individual routes making
their display and handling by userspace different and more complicated
than IPv4, putting the burden on the user to see that a route is part of
a multipath route and internally creating a multipath route if desired
(e.g., libnl does this as of commit 29b71371e764). This patch addresses
this difference, allowing multipath routes to be returned using the
RTA_MULTIPATH attribute.
The end result is that IPv6 multipath routes can be treated and displayed
in a format similar to IPv4:
$ ip -6 ro ls vrf red
2001:db8:1::/120 dev eth1 proto kernel metric 256 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium

IPv4 allows multipath routes to be deleted using just the prefix and
length. For example:
$ ip ro ls vrf red
unreachable default metric 8192
1.1.1.0/24
nexthop via 10.100.1.254 dev eth1 weight 1
nexthop via 10.11.200.2 dev eth11.200 weight 1
10.11.200.0/24 dev eth11.200 proto kernel scope link src 10.11.200.3
10.100.1.0/24 dev eth1 proto kernel scope link src 10.100.1.3
$ ip ro del 1.1.1.0/24 vrf red
$ ip ro ls vrf red
unreachable default metric 8192
10.11.200.0/24 dev eth11.200 proto kernel scope link src 10.11.200.3
10.100.1.0/24 dev eth1 proto kernel scope link src 10.100.1.3
The same notation does not work with IPv6 because of how multipath routes
are implemented for IPv6. For IPv6 only the first nexthop of a multipath
route is deleted if the request contains only a prefix and length. This
leads to unnecessary complexity in userspace dealing with IPv6 multipath
routes.
This patch allows all nexthops to be deleted without specifying each one
in the delete request. Internally, this is done by walking the sibling
list of the route matching the specifications given (prefix, length,
metric, protocol, etc).
$ ip -6 ro ls vrf red
2001:db8:1::/120 dev eth1 proto kernel metric 256 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium
2001:db8:200::/120 via 2001:db8:1::2 dev eth1 metric 1024 pref medium
2001:db8:200::/120 via 2001:db8:2::2 dev eth2 metric 1024 pref medium
...
$ ip -6 ro del vrf red 2001:db8:200::/120
$ ip -6 ro ls vrf red
2001:db8:1::/120 dev eth1 proto kernel metric 256 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium
...
Because IPv6 allows individual nexthops to be deleted without deleting
the entire route, the ip6_route_multipath_del and non-multipath code
path (ip6_route_del) have to be discriminated so that all nexthops are
only deleted for the latter case. This is done by making the existing
fc_type in fib6_config a u16 and then adding a new u16 field with
fc_delete_all_nh as the first bit.

Here are two bugfixes that resolve some reported issues. One in the
firmware loader, that should fix the much-reported problem of crashes
with it. The other is a hyperv fix for a reported regression.
Both have been in linux-next for a week or so with no reported issues.

40GbE Intel Wired LAN Driver Updates 2017-02-03
This series contains updates to i40e/i40evf only.
Jake fixes up the driver to not call i40e_vsi_kill_vlan() or
i40e_vsi_add_vlan() when the PVID is set or when the VID is less than 1.
Cleaned up a check which really is not needed since there is no real
reason why we cannot just call i40e_del_mac_all_vlan() directly. Renamed
functions to better reflect their actual purpose and how they function
in a more clear manner.
Bimmy cleans up unused/deprecated macros.
Mitch cleans up unused device ids which were intended for use when
running Linux VF drivers under Hyper-V, but found to be not needed.
Then cleaned up a function that is no longer needed since the client
open and close functions were refactored. Adds a sleep without timeout
until the reply from the PF driver has been received since the iWARP
client cannot continue until the operation has been completed.
Tushar Dave fixes an issue seen on SPARC where the use of the 'packed'
directive was causing kernel unaligned errors.
Alex does a refactor to pull some data off of the stack and store it
in the transmit buffer info section of the transmit ring.
Alan fixes a bug which was caused by passing a bad register value to the
firmware, by refactoring the macro INTRL_USEC_TO_REG into a static
inline function. Also added feedback to the user as to the actual
interrupt rate limit being used when it differs from the requested limit.
