This is a re-post of previous patch wrote by David Miller[1].
Phil Karn reported[2] that on busy networks with lots of unresolved
multicast routing entries, the creation of new multicast group routes
can be extremely slow and unreliable.
The reason is we hard-coded multicast route entries with unresolved source
addresses(cache_resolve_queue_len) to 10. If some multicast route never
resolves and the unresolved source addresses increased, there will
be no ability to create new multicast route cache.
To resolve this issue, we need either add a sysctl entry to make the
cache_resolve_queue_len configurable, or just remove cache_resolve_queue_len
limit directly, as we already have the socket receive queue limits of mrouted
socket, pointed by David.
>From my side, I'd perfer to remove the cache_resolve_queue_len limit instead
of creating two more(IPv4 and IPv6 version) sysctl entry.
[1] https://lkml.org/lkml/2018/7/22/11
[2] https://lkml.org/lkml/2018/7/21/343
v3: instead of remove cache_resolve_queue_len totally, let's only remove
the hard code limit when allocate the unresolved cache, as Eric Dumazet
suggested, so we don't need to re-count it in other places.
v2: hold the mfc_unres_lock while walking the unresolved list in
queue_count(), as Nikolay Aleksandrov remind.

VF NIC may go down then come up during host servicing events. This
causes the VF NIC offloading feature settings to roll back to the

100GbE Intel Wired LAN Driver Updates 2019-09-05
This series contains updates to ice driver.
Brett fixes the setting of num_q_vectors by using the maximum number
between the allocated transmit and receive queues.
Anirudh simplifies the code to use a helper function to return the main
VSI, which is the first element in the pf->vsi array. Adds a pointer
check to prevent a NULL pointer dereference. Adds a check to ensure we
do not initialize DCB on devices that are not DCB capable. Does some
housekeeping on the code to remove unnecessary indirection and reduce
the PF structure by removing elements that are not needed since the
values they were storing can be readily gotten from
ice_get_avail_*_count()'s. Updates the printed strings to make it
easier to search the logs for driver capabilities.
Jesse cleans up unnecessary function arguments. Updated the code to use
prefetch() to add some efficiency to the driver to avoid a cache miss.
Did some housekeeping on the code to remove the configurable transmit
work limit via ethtool which ended up creating performance overhead.
Made additional performance enhancements by updating the driver to start
out with a reasonable number of descriptors by changing the default to
2048.
Mitch fixes the reset logic for VFs by clearing VF_MBX_ARQLEN register
when the source of the reset is not PFR.
Lukasz updates the driver to include a similar fix for the i40e driver
by reporting link down for VF's when the PF queues are not enabled.
Akeem updates the driver to report the VF link status once we get VF
resources so that we can reflect the link status similarly to how the PF
reports link speed.
Ashish updates the transmit context structure based on recent changes to
the hardware specification.
Dave updates the DCB logic to allow a delayed registration for MIB
change events so that the driver is not accepting events before it is
ready for them.

The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add the ability to use unaligned chunks in the AF_XDP umem. By
relaxing where the chunks can be placed, it allows to use an
arbitrary buffer size and place whenever there is a free
address in the umem. Helps more seamless DPDK AF_XDP driver
integration. Support for i40e, ixgbe and mlx5e, from Kevin and

2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
application can wake up the kernel for rx/tx processing which
avoids busy-spinning of the latter, useful when app and driver
is located on the same core. Support for i40e, ixgbe and mlx5e,
from Magnus and Maxim.
3) bpftool fixes for printf()-like functions so compiler can actually
enforce checks, bpftool build system improvements for custom output
directories, and addition of 'bpftool map freeze' command, from Quentin.
4) Support attaching/detaching XDP programs from 'bpftool net' command,
from Daniel.
5) Automatic xskmap cleanup when AF_XDP socket is released, and several
barrier/{read,write}_once fixes in AF_XDP code, from Björn.
6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf
inclusion as well as libbpf versioning improvements, from Andrii.
7) Several new BPF kselftests for verifier precision tracking, from Alexei.
8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya.

It looks like when loopback is enabled the PHY will report that Link is

As in loopback mode the data will not be sent anywhere we can bypass the

For high speed adapter like Mellanox CX-5 card, it can reach upto
100 Gbits per second bandwidth. Currently htb already supports 64bit rate
in tc utility. However police action rate and peakrate are still limited
to 32bit value (upto 32 Gbits per second). Add 2 new attributes
TCA_POLICE_RATE64 and TCA_POLICE_RATE64 in kernel for 64bit support
so that tc utility can use them for 64bit rate and peakrate value to
break the 32bit limit, and still keep the backward binary compatibility.

Offloaded OvS datapath rules are translated one to one to tc rules,
for example the following simplified OvS rule:
recirc_id(0),in_port(dev1),eth_type(0x0800),ct_state(-trk) actions:ct(),recirc(2)
Will be translated to the following tc rule:
$ tc filter add dev dev1 ingress \
prio 1 chain 0 proto ip \
flower tcp ct_state -trk \
action ct pipe \
action goto chain 2
Received packets will first travel though tc, and if they aren't stolen
by it, like in the above rule, they will continue to OvS datapath.
Since we already did some actions (action ct in this case) which might
modify the packets, and updated action stats, we would like to continue
the proccessing with the correct recirc_id in OvS (here recirc_id(2))
where we left off.
To support this, introduce a new skb extension for tc, which
will be used for translating tc chain to ovs recirc_id to
handle these miss cases. Last tc chain index will be set
by tc goto chain action and read by OvS datapath.

Use cancel_delayed_work_sync on the dump workers only in case of
unloading the op mode. In any other case use iwl_fw_flush_dumps or
iwl_fw_dbg_stop_sync (depends if the op mode mutex is held or not).
This way, the driver will wait until debug data is collected in all
cases but op mode unloading.

Remove the "apply points" mechanism as preparation for the changed
debug API where this is now a "time point" instead. Use a new API
across the code at the trigger points ("time points"), but don't
yet implement it since that requires some more preparation.

Sometimes the firmware won't be able to decrypt frames
because the keys were not installed yet or other scenarios.
The firmware will soon stop dropping multicast frames when
MAC_FILTER_ACCEPT_GRP is not set. The firmware will simply
always pass multicast frame in.
In order to avoid logging any such frame coming in when we
don't have the keys, drop the print.

There are products which have a single chain with 2 antennas.
In these products, we need to inform the FW that the device has the
single antenna diversity(SAD) feature. In the future, we will read
the active antenna from a BIOS configuration. Currently, we use a
default configuration which means that the FW decides which antenna to use.

In prior hardware generations (e.g. 9000 series), we received the BAR
frame with fake NSSN information to handle releasing frames from the
reorder buffer for the default queue, the other queues were getting
the FRAME_RELEASE notification in this case.
With multi-TID block-ack, the firmware no longer sends us the BAR
frame because the fake RX is quite big (just the metadata is around
48 bytes or so). Instead, it now sends us one (or multiple) special
release notifications (0xc2). The hardware consumes these as well,
but only generates the FRAME_RELEASE (0xc3) for queues other than
the default queue. We thus need to handle them in the same way we
handle the normal FRAME_RELEASE.

Certain APs (I think a certain Broadcom model) interact badly with our
full state BA bitmap handling, and if triggered badly with many powersave
transitions they keep sending frames from before the window, which our
hardware then doesn't appear to ACK (to them) since it has moved on and
is sending ACKs for higher SNs now.
Try to detect this situation and if this keeps happening, disable the
aggregation session.
