Currently there is no way for a VF driver to specify if it wants to change it's hardware address. New bits are being added to virtchnl.h in struct virtchnl_ether_addr that allow for the VF to correctly communicate this information. However, legacy VF drivers that don't support the new virtchnl.h bits still need to be supported. Make a best effort attempt at saving the VF's primary/device address in the legacy case and depend on the VIRTCHNL_ETHER_ADDR_PRIMARY type for the new case. Legacy case - If a unicast MAC is being added and the hw_lan_addr.addr is empty, then populate it. This assumes that the address is the VF's hardware address. If a unicast MAC is being added and the hw_lan_addr.addr is not empty, then cache it in the legacy_last_added_umac.addr. If a unicast MAC is being deleted and it matches the hw_lan_addr.addr, then zero the hw_lan_addr.addr. Also, if the legacy_last_added_umac.addr has not expired, copy the legacy_last_added_umac.addr into the hw_lan_addr.addr. This is done because we cannot guarantee the order of VIRTCHNL_OP_ADD_ETH_ADDR and VIRTCHNL_OP_DEL_ETH_ADDR. New case - If a unicast MAC is being added and it's specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then replace the current hw_lan_addr.addr. If a unicast MAC is being deleted and it's type is specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then zero the hw_lan_addr.addr. Untrusted VFs - Only allow above legacy/new changes to their hardware address if the PF has not set it administratively via iproute2. Trusted VFs - Always allow above legacy/new changes to their hardware address even if the PF has administratively set it via iproute2. Also, change the variable dflt_lan_addr to hw_lan_addr to clearly represent the purpose of this variable since it's purpose is to act as a hardware programmed MAC address for the VF.
