Merge branch 'qed-Light-L2-updates'

Yuval Mintz says:

====================
qed*: Light L2 updates

This series does a major overhaul of the LL2 logic in qed.
The single biggest change done here is in #5 where we're changing
the API qed provides for LL2 [both internally in case of storage and
externally in case of RoCE] to become callback-based to allow cleaner
scalability in preperation to the future iWARP submission which would
aadd additional flavors of LL2. It's also the only patch in series
to modify !qed logic [qedr].

Patches prior to that mostly deal with refactoring LL2 code,
encapsulating varaious parameters into structure and re-ordering
of LL2 code. The latter patches add some small missing bits of LL2
ffunctionality.
