Merge branch 'qed-XDP-support' 

Yuval Mintz says:

====================
qed*: Add XDP support

This patch series is intended to add XDP to the qede driver, although
it contains quite a bit of cleanups, refactorings and infrastructure
changes as well.

The content of this series can be roughly divided into:

 - Datapath improvements - mostly focused on having the datapath utilize
parameters which can be more tightly contained in cachelines.
Patches #1, #2, #8, #9 belong to this group.

 - Refactoring - done mostly in favour of XDP. Patches #3, #4, #5, #9.

 - Infrastructure changes - done in favour of XDP. Paches #6 and #7 belong
to this category [#7 being by far the biggest patch in the series].

 - Actual XDP support - last two patches [#10, #11].
====================
