====================
mlx4: Fix VF MAC address change under RoCE usage
This short series provides proper handling for the case where a
VF netdevice change their MAC address under a RoCE use case. The code
it deals with was introduced in 3.15-rc1
Prior to this series the source MAC used for the VM RoCE CM
packets remains as before the MAC modification. Hence RoCE CM
packets sent by the VF will not carry the same source MAC
address as the non-CM packets.
Earlier 3.15-rc commit f24f790 "net/mlx4_core: Load the Eth driver
first" handled just one instance of the problem, but this one
provides a more generic and proper solution which covers all
cases of VF mac change.
