Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

New generation devices have firmware which has more than 256 flowrings.
E.g. following debugging message comes from 14e4:4365 BCM4366:
[  194.606245] brcmfmac: brcmf_pcie_init_ringbuffers Nr of flowrings is 264

At various code places (related to flowrings) we were using u8 which
could lead to storing wrong number or infinite loops when indexing with
this type. This issue was quite easy to spot in brcmf_flowring_detach
where it led to infinite loop e.g. on failed initialization.

This patch switches code to proper types and increases the maximum
number of supported flowrings to 512.

Originally this change was sent in September 2015, but back it was
causing a regression on BCM43602 resulting in:
Unable to handle kernel NULL pointer dereference at virtual address ...

The reason for this regression was missing update (s/u8/u16) of struct
brcmf_flowring_ring. This problem was handled in 9f64df94 ("brcmfmac: Fix
bug in flowring management."). Starting with that it's safe to apply
this original patch as it doesn't cause a regression anymore.

This patch fixes an infinite loop on BCM4366 which is supported since
4.4 so it makes sense to apply it to stable 4.4+.

40GbE Intel Wired LAN Driver Updates 2016-02-18

This series contains updates to i40e and i40evf only.

Alex Duyck provides all the patches in the series to update and fix the
drivers.  Fixed the driver to drop the outer checksum offload on UDP
tunnels, since the issue is that the upper levels of the stack never
requested such an offload and it results in possible errors.  Updates the
TSO function to just use u64 values, so we do not have to end up casting
u32 values.  In the TSO path, factored out the L4 header offsets allowing
us to ignore the L4 header offsets when dealing with the L3 checksum and
length update.  Consolidates all of the spots where we were updating
either the TCP or IP checksums in the TSO and checksum path into the TSO
function.  Fixed two issues by adding support for IPv4 encapsulated in
IPv6, first issue was the fact that iphdr(skb)->protocol was being used to
test for the outer transport protocol which breaks IPv6 support.  The second
was that we cleared the flag for v4 going to v6, but we did not take care
of txflags going the other way.  Added support for IPv6 extension headers
in setting up the Tx checksum.  Added exception handling to the Tx
checksum path so that we can handle cases of TSO where the frame is bad,
or Tx checksum where we did not recognize a protocol.  Fixed a number of
issues to make certain that we are using the correct protocols when
parsing both the inner and outer headers of a frame that is mixed between
IPv4 and IPv6 for inner and outer.  Updated the feature flags to reflect
the newly enabled/added features.

Sorry, no witty patch descriptions this time around, probably should
let Mitch help in writing patch descriptions for Alex. :-)

Recent changes should have enabled support for IPv6 based tunnels and
support for TSO with outer UDP checksums.  As such we can update the
feature flags to reflect that.

In addition we can clean-up the flags that aren't needed such as SCTP and
RXCSUM since having the bits there doesn't add any value.

I also found one spot where we were setting the same flag twice.  It looks
like it was probably a git merge error that resulted in the line being
duplicated.  As such I have dropped it in this patch.

All of the documentation in the datasheets for the XL710 do not call out
any reason to exclude support for IPv6 based tunnels.  As such I am
dropping the code that was excluding these tunnel types from having their
port numbers recognized.  This way we can take advantage of things such as
checksum offload for inner headers over IPv6 based VXLAN or GENEVE
tunnels.
