Merge branch 'be2net-next'

Sriharsha Basavapatna says:

====================
be2net patch-set

This patch set contains a few code refactoring changes to make it easy to
support new TX WRB formats in future ASICs. Please consider applying it to
net-next tree.

Patch 1: Refactors chip specific code to setup tx wrb into a separate routine.
Patch 2: Refactors tx enqueue function to remove a bit of duplicate code and
	 improves wrb setup steps.
Patch 3: Minor refactoring in tx compl to limit CQE accesses to 1 routine.
Patch 4: Adds a few inline functions.
