64c75d41ac igb: support RX flow classification by ethertype
This patch is meant to allow for RX network flow classification to insert
and remove ethertype filter by ethtool

Example:
Add an ethertype filter:
$ ethtool -N eth0 flow-type ether proto 0x88F8 action 2

Show all filters:
$ ethtool -n eth0
4 RX rings available
Total 1 rules

Filter: 15
	Flow Type: Raw Ethernet
	Src MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF
	Dest MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF
	Ethertype: 0x88F8 mask: 0x0
	Action: Direct to queue 2

Delete the filter by location:
$ ethtool -N delete 15

a51d8c217b igb: use BIT() macro or unsigned prefix
For bitshifts, we should make use of the BIT macro when possible, and
ensure that other bitshifts are marked as unsigned. This helps prevent
signed bitshift errors, and ensures similar style.

Make use of GENMASK and the unsigned postfix where BIT() isn't
appropriate.

c883de9fd7 igb: rename igb define to be more generic
E1000_MRQC_ENABLE_RSS_4Q enables 4 and 8 queues depending on the part
so rename to be generic.

Similarly, E1000_MRQC_ENABLE_VMDQ_RSS_2Q has no numeric meaning so
rename to be more generic.

dc1edc67fe igb: enable VLAN stripping for VMs with i350
For i350 VLAN stripping for VMs is not enabled in the VMOLR register but in
the DVMOLR register. Making the changes accordingly. It's not necessary to
unset the E1000_VMOLR_STRVLAN bit on i350 as the hardware will simply ignore
it.

Without this change if a VLAN is configured for a VF assigned to a guest
via (i.e.)
ip link set p1p1 vf 0 vlan 10
the VLAN tag will not be stripped from packets going into the VM. Which they
should be because the VM itself is not aware of the VLAN at all.

f4c01e965f igb: Fix for devices using ethtool for EEE settings
This patch fixes a problem where using ethtool for EEE setting was not
working correctly.  This patch also fixes a problem where
the function that checks for EEE status on i354 devices was not being
called and was causing warnings with static analysis tools.

5ccc921af4 intel: Remove extern from function prototypes
There are a mix of function prototypes with and without extern
in the kernel sources.  Standardize on not using extern for
function prototypes.

Function prototypes don't need to be written with extern.
extern is assumed by the compiler.  Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

In addition I am enabling relaxed ordering for reads from hardware since
