My first guess is that you are programming the filter incorrectly in
your MAC chip. It could be you are blocking the broadcast address, or
the unicast address for your device. Is the DHCP server broadcasting
is response, or unicasting it?


Shouldn't the upper layer provide broadcast address in the list to
ETH_DRV_SET_MC_LIST if it wants to receive broadcast packets? My guess
it is upper layer responsibility to do so, because of otherwise I do
not see any sense for that call...
