Relax ordering(RO) is one feature of 82599 NIC, to enable this feature can
enhance the performance for some cpu architecure, such as SPARC and so on.
Currently it only supports one special cpu architecture(SPARC) in 82599
driver to enable RO feature, this is not very common for other cpu architecture
which really needs RO feature.
This patch add one common config CONFIG_ARCH_WANT_RELAX_ORDER to set RO feature,
and should define CONFIG_ARCH_WANT_RELAX_ORDER in sparc Kconfig firstly.

There are two problems with EEPROM access. One is that it needs to
hold the semaphore until the entire response is read or else the
response can be corrupted by other firmware accesses. The second
problem is that acquiring and releasing the semaphore is slow, so
it should be taken and released once when multiple EEPROM accesses
will be done.
Both of these issues can be solved by adding a new function,
ixgbe_hic_unlocked, to issue firmware commands that will assume
that the caller has acquired the needed semaphore.

This patch address a few issues with the initial crosstalk fix. Most
important of which is the SDP that indicates the presents of a SFP+
module changes between HW types. With this change that is taken in

It also moves the check closer to the base code that checks link. This
makes it so we only need to do the check in one spot.

Several areas of ixgbe were written before widespread usage of the
BIT(n) macro. With the impending release of GCC 6 and its associated new
warnings, some usages such as (1 << 31) have been noted within the ixgbe
driver source. Fix these wholesale and prevent future issues by simply
using BIT macro instead of hand coded bit shifts.
Also fix a few shifts that are shifting values into place by using the
'u' prefix to indicate unsigned. It doesn't strictly matter in these
cases because we're not shifting by too large a value, but these are all
unsigned values and should be indicated as such.

Consolidate the logic behind configuring spoof checking:
Move the setting of the MAC, VLAN and Ethertype spoof checking into
ixgbe_ndo_set_vf_spoofchk().
Change ixgbe_set_mac_anti_spoofing() to set MAC spoofing per VF similar
to the VLAN and Ethertype functions - this allows us to call the helper
functions in ixgbe_ndo_set_vf_spoofchk() for all spoof check types and
only disable MAC spoof checking when creating MACVLAN.

This patch is meant to reduce the complexity of the search function used
for finding a VLVF entry associated with a given VLAN ID. The previous
code was searching from bottom to top. I reordered it to search from top
to bottom. In addition I pulled an AND statement out of the loop and
instead replaced it with an OR statement outside the loop. This should
help to reduce the overall size and complexity of the function.
There was also some formatting I cleaned up in regards to whitespace and
such.

This patch adds support for bypassing the VLVF entry creation when the PF
is adding a new VLAN. The advantage to doing this is that we can then save
the VLVF entries for the VFs which must have them in order to function,
versus the PF which can fall back on the default pool entry.

This patch addresses several issues within the VLVF and VLVFB
configuration
First was the fact that code was overly complicated with multiple
conditional paths depending on if we adding or removing and which bit we
were going to add or remove. Instead of messing with all that I have
simplified it by using (vid / 32) and (1 - vid / 32) to identify our
register and the other vlvfb register.
Second was the fact that we were likely leaking a few packets into the PF
in cases where we were deleting an entry and the VFTA filter for that entry
as the ordering was such that we deleted the pool and then the VLAN filter
instead of the other way around. I have updated that by adding a check for
no bits being set and if that occurs we clear things up in the proper
order.

In order to clear the way for upcoming work I thought it best to drop the
level of indent in the ixgbe_set_vfta_generic function. Most of the code
is held in the virtualization specific section. So the easiest approach is
to just add a jump label and jump past the bulk of the code if it is not
enabled.

Currently the shared code checksum calculation function only
returns a u16 and cannot return an error code. Unfortunately
a variety of errors can happen that completely prevent the

positive checksum value when there is no error.
