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
