Subject: [PATCH net-next 13/13] ice: remove unnecessary virtchnl_ether_addr struct use

From: Jacob Keller <jacob.e.keller@...el.com>

The dev_lan_addr and hw_lan_addr members of ice_vf are used only to store
the MAC address for the VF. They are defined using virtchnl_ether_addr, but
only the .addr sub-member is actually used. Drop the use of
virtchnl_ether_addr and just use a u8 array of length [ETH_ALEN].
