Issue: DHCP server will send DHCP offer/ack via broadcast packet if broadcast flag is enabled in DHCP discover/request. There's no retransmition mechanism for broadcast frame in 802.11 MAC layer, thus transmit fail rate might be very high. This will increase DHCP fail rate. Solution: Disable broadcast flag by default Signed-off-by: liangchaozhong <liangchaozhong@xiaomi.com>
