  To: dev; +Cc: Qi Zhang, Guinan Sun

Due to the restriction of the flag I40E_FLAG_VF_MAC_BY_PF,
VF cannot program the MAC address.
In order to solve this inflexibility, the use of I40E_FLAG_VF_MAC_BY_PF
has been deleted in the code implementation to ensure that
VF can flexibly program the MAC address.
