The current logic around the 'use_dac' module parameter prevents the
r81969 driver from being loadable on 64-bit systems without any RAM
below 4 GB when the parameter is left at its default value.
So introduce a new default value -1 which indicates that 64-bit DMA
should be enabled on sufficiently recent PCIe chips, i.e., versions
RTL_GIGA_MAC_VER_18 or later. Explicit param values of 0 or 1 retain
the existing behavior of unconditionally enabling/disabling 64-bit DMA
on 64-bit architectures (i.e., regardless of the type and version of the
chip)
Since PCIe chips do not need to CPlusCmd Dual Address Cycle to be set,
make that conditional on the device type as well.

The problem is that fib_info->nh is [0] so the struct fib_info
allocation size depends on number of nexthops. If we just copy fib_info,
we do not copy the nexthops info and driver accesses memory which is not
ours.
Given the fact that fib4 does not defer operations and therefore it does
not need copy, just pass the pointer down to drivers as it was done
before.

This patch adds the necessary driver support for Management Firmware to
configure the device/firmware with the dcbx results. Management Firmware
is responsible for communicating the DCBX and driving the negotiation,
but the driver has responsibility of receiving async notification and
configuring the results in hw/fw. This patch also adds the dcbx support for
future protocols (e.g., FCoE) as preparation to their imminent submission.

When reopening the network device on ra7795/salvator-x, e.g. after a

The "mismatch" is due to requesting an IRQ that is already in use,

It looks like at some point I somehow transposed the location of setting
the VLAN features in netdev->features and the configuration of the
vlan_features. As a result the driver is now generating a warning about
vlan_features being setup incorrectly.
This patch corrects that by placing the update of netdev->features to
include the VLAN features so that it is after the point where we write
netdev->features into netdev->vlan_features.

PF updates its VFs' bulletin boards with link configurations whenever
the physical carrier changes or whenever hyper-user explicitly requires
some setting of the VFs link via the hypervisor's PF.
Since the bulletin board is getting cleaned as part of the IOV disable
flow on the PF side, re-enabling sriov would lead to a VF that sees the
carrier as 'down', until an event causing the PF to re-fill the bulletin
with the link configuration would occur.
To fix this we simply refelect the link state during the flows, giving
the later VFs a default reflecting the PFs link state.

If a counter has the aging flag set when created, it is added to a list
of counters that will be queried periodically from a workqueue. query
result and last use timestamp are cached.
add/del counter must be very efficient since thousands of such
operations might be issued in a second.
There is only a single reference to counters without aging, therefore
no need for locks.
But, counters with aging enabled are stored in a list. In order to make
code as lockless as possible, all the list manipulation and access to
hardware is done from a single context - the periodic counters query
thread.
The hardware supports multiple counters per FTE, however currently we
are using one counter for each FTE.

40GbE Intel Wired LAN Driver Updates 2016-05-14
This series contains updates to i40e and i40evf.
Kevin adds support to disable link on all ports and changes bits set
for telling firmware the PHY needs to be modified by the driver.
Anjali adds a feature to enable/disable all multicast for a trusted
VF. Added priv-flag knob to configure global true promiscuous
support.
Shannon adds the support code for calling the admin queue API call
aq_set_switch_config().
Mitch modifies the VF, to log a message if an untrusted VF attempts to
configure promiscuous mode, but lies to it and returns everything is ok
instead of returning an error. Corrects the logic for reporting the
receive packet hash. Fixed the adding of a broadcast filter for VFs,
since that all VSIs are configured to receive broadcasts as default,
so do not need to add a filter.
Catherine refactors the ethtool get_settings to report the possible
supported link modes from what we know about the current PHY type and
that with the firmware supported PHY types.
Jacob changes the driver to use WARN_ONCE in order to highlight the
issue, but do not display a warning every time when receive hang
message is received.
Akeem corrects receive ptype payload layer for non_tunneled IPv6, when
it should be layer 4 for UDP, instead of layer 3.

The current code has 2 problems:
1. The maximum wait time is not long enough. It is about 60% of the
duration specified by the firmware. It is calling usleep_range(600, 800)
for every 1 msec we are supposed to wait.
2. The granularity of the delay is too coarse. Many simple firmware
commands finish in 25 usec or less.
We fix these 2 issues by multiplying the original 1 msec loop counter by
40 and calling usleep_range(25, 40) for each iteration.
There is also a second delay loop to wait for the last DMA word to
complete. This delay loop should be a very short 5 usec wait.
This change results in much faster bring-up/down time:

time ip link set p4p1 up
