Merge branch 'qed-driver-updates'
Yuval Mintz says:
====================
qed*: Driver updates
The more interesting changes in this series include:
- Restructuring of the qede files - qede_main.c has grown big and this
series splits it into 3 parts [patches #2 and #3].
- Some significant changes in the API through which RSS indirection
table gets configured [#8].
- Support for ndo_set_vf_trust() [#9] which would regulate which VFs
are allowed to use promisc/multi-promisc mode.
It also contains various minor changes to qed/qede, as well as
non-functional changes [#1, #12] to complement other changes.
