iavf: remove INITIAL_MAC_SET to allow gARP to work properly
IAVF_FLAG_INITIAL_MAC_SET prevents waiting on iavf_is_mac_set_handled()
the first time the MAC is set. This breaks gratuitous ARP because the
MAC address has not been updated yet when the gARP packet is sent out.
Current behaviour:
$ echo 1 > /sys/class/net/ens4f0/device/sriov_numvfs
iavf 0000:88:02.0: MAC address: ee:04:19:14:ec:ea
$ ip addr add 192.168.1.1/24 dev ens4f0v0
$ ip link set dev ens4f0v0 up
$ echo 1 > /proc/sys/net/ipv4/conf/ens4f0v0/arp_notify
$ ip link set ens4f0v0 addr 00:11:22:33:44:55
07:23:41.676611 ee:04:19:14:ec:ea > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 42: Request who-has 192.168.1.1 tell 192.168.1.1, length 28
With IAVF_FLAG_INITIAL_MAC_SET removed:
$ echo 1 > /sys/class/net/ens4f0/device/sriov_numvfs
iavf 0000:88:02.0: MAC address: 3e:8a:16:a2:37:6d
$ ip addr add 192.168.1.1/24 dev ens4f0v0
$ ip link set dev ens4f0v0 up
$ echo 1 > /proc/sys/net/ipv4/conf/ens4f0v0/arp_notify
$ ip link set ens4f0v0 addr 00:11:22:33:44:55
07:28:01.836608 00:11:22:33:44:55 > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 42: Request who-has 192.168.1.1 tell 192.168.1.1, length 28
