The NVMUpdate tool doesn't necessarily know the ReadOnly map of the current
NVM image, and must try reading and writing words that may be protected.
This generates an error out of the Firmware request that the driver logs.
Unfortunately, this ends up spitting out hundreds of bogus read and write
error message that looks rather messy.
This patch checks the error type and under normal conditions will not print
the typical read and write errors during NVMUpdate. This can be overridden
by enabling the NVM update debugging. This results in a much less messy log
file, and likely many fewer customer support questions.

Since GLQF_FDCNT_0 register now has the right offset, use it to simplify our
FD flush flow.
If the filter add error happens to be for SB we just auto disable SB.
If filter error happens to be for ATR, auto disable ATR and mark
the state to FD_FLUSH_REQUESTED. Which gets cleared when flush completes.
If we are entering flush too quickly (< 30 seconds) and we have quite
a few SB rules, its time to disable ATR for good. Since SB + ATR rules
is most likely making the FD table unstable.
ATR can be re-enabled by turning ntuple off (ethtool -K ntuple off)
and will remain off after turning ntuple on till it gets unstable again.

The initial problem solved here is that the vector allocation was trying
too hard to save vectors for VMDq, to the point of not giving the PF enough
when in a tight situation such as an NPAR partition. This change makes
sure that the PF will get all the queues and vectors it wants to fill
out its destiny. Essentially, nothing is specially reserved for VMDq,
it simply gets whatever is left after the PF, FCoE, and FD sideband get
what they want.
Additionally, the calculations for the reservations were harder to follow
than necessary, so I've made it more straight forward.

Intel Wired LAN Driver Updates 2015-03-03
This series contains updates to fm10k, i40e and i40evf.
Matthew updates the fm10k driver by cleaning up code comments and whitespace
issues. Also modifies the tunnel length header check, to make it more robust
by calculating the inner L4 header length based on whether it is TCP or UDP.
Implemented ndo_features_check() that allows drivers to report their offload
capabilities per-skb.
Neerav updates the i40e driver to skip over priority tagging if DCB is not
enabled. Fixes an issue where the driver is not flushing out the
DCBNL app table for applications that are not present in the local DCBX
application configuration TLVs. Fixed i40e where, in the case of MFP
mode, the driver was returning the incorrect number of traffic classes
for partitions that are not enabled for iSCSI. Even though the driver
was not configuring these traffic classes in the transmit scheduler for
the NIC partitions, it does use this map to setup the queue mappings.
Shannon updates i40e/i40evf to include the firmware build number in the
formatted firmware version string.
Akeem adds a safety net (by adding a 'default' case) for the possible
unmatched switch calls.
Mitch updates i40e to not automatically disable PF loopback at runtime,
now that we have the functionality to enable and disable PF loopback. This
fix cleans up a bogus error message when removing the PF module with VFs
enabled. Adds a extra check to make sure that the indirection table
pointer is valid before dereferencing it.
Anjali enables i40e to enable more than the max RSS qps when running in a
single TC mode for the main VSI. It is possible to enable as many as
num_online_cpus(). Adds a firmware check to ensure that DCB is disabled for
firmware versions older than 4.33. Updates i40e/i40evf to add missing
packet types for VXLAN offload. Updated i40e to be able to handle varying
RSS table size for each VSI, since all VSI's do not have the same RSS table
size.
v2: Dropped previous patch #9 "i40e/i40evf: Add capability to gather VEB
per TC stats" since the stats should be in ethtool and not debugfs.

With changes to default number of queue pairs that the interface comes up with
from 1 per online CPU to 1 per lan_msix, we need to make sure we recalculate
rss_size. We will now recalculate rss_size based on number of queues enabled in
the VSI.
Without this fix if the max_lan_msix < num_online_cpu we will be coming up
with fewer queues but will be populating rss_size based on num_online_cpus.
This will result in packets getting silently dropped because RSS LUT has queues
that are not enabled.
