> If the Freescale fec is in promiscuous mode and network cable is
> reconnected then the promiscuous mode get lost. The problem is caused
> by a too soon call of set_multicast_list to re-enable promisc mode.
> The FEC_R_CNTRL register changes are overwritten by fec_restart.
> 
> This patch fixes this by moving the call behind the init of FEC_R_CNTRL
> register in fec_restart.
