Merge branch 'qed-sriov'

Yuval Mintz says:

====================
qed*: Add SR-IOV support

This patch adds SR-IOV support to qed/qede drivers, adding a new PCI
device ID for a VF that is shared between all the various PFs that
support IOV.

This is quite a massive series - the first 7 parts of the series add
the infrastructure of supporting vfs in qed - mainly adding support in a
HW-based vf<->pf channel, as well as diverging all existing configuration
flows based on the pf/vf decision. I.e., while PF-originated requests
head directly to HW/FW, the VF requests first have to traverse to the PF
which will perform the configuration.

The 8th patch is the one that adds the support for the VF device in qede.

The remaining 6 patches each adds some user-based API support related to
VFs that can be used over the PF - forcing mac/vlan, changing speed, etc.

Dave,

Sorry in advance for the length of the series. Most of the bulk here is in
the infrastructure patches that have to go together [or at least, it makes
little sense to try splitting them up].

Please consider applying this to `net-next'.

Thanks,
Yuval

Changes from previous revision:
------------------------------
 - V2 - Replace aligned_u64 with regular u64; This was possible as the
        shared structures [between PF and VF] were already sufficiently
        padded as-is in the API, making this redundant.
