====================
qlcnic: SR-IOV and FW-dump enhancements

This patch series contain following enhancements.

* SR-IOV enhancements:
- Allow SR-IOV VF's to probe in hypervisor. SR-IOV VF can be
uplinked to bridge/macvtap device with this change.
- Commands from VF are processed in process context
as it may sleep during PF-VF communication. Earlier
we use to process qlcnic_sriov_vf_set_multi function in
process context but now we process individual commands.
- As SR-IOV VF's can be uplinked to bridge/macvtap device
support mac-learning to allow communication through
embedded switch.

* FW-dump enhancement:
- Support to collect RDMEM section of firmware dump using
PEX DMA method for 82xx series adapter.

* Changes in v2:
- Removed unnecessary cast from void pointer to something
else and verified this issue in entire patch series as
per David Miller's suggestion.

Please apply this series to net-next.
