FID is directly mapped to VID. However, configuring a MAC address with a
VID != 0 resulted in incorrect configuration due to an incorrect bit
mask. This kernel commit fixed the issue by correcting the bit mask and
ensuring proper configuration of MAC addresses with non-zero VID.

Cross verified the bit mask with datasheet.
Patch Looks good to me.
