Hello

Today, when I was looking through my csb337 port of u-boot trying to make it ready for u-boot inclusion, I found a strange thing in the at91rm9200 ethernet driver (cpu/arm920t/at91rm9200/ether.c). The driver is running in promiscuous mode (CAF: Copy All Frames) and reception of broadcast packages are not enabled (NBC: No Broadcast) around line 206:

p_mac->EMAC_CFG = (p_mac->EMAC_CFG | AT91C_EMAC_CAF | AT91C_EMAC_NBC) & ~AT91C_EMAC_CLK;

Since I do not want to run in promiscuous mode, I tried to fix it by removing AT91C_EMAC_CAF. I still want to receive broadcast packages (e.g dhcp offers etc) so AT91C_EMAC_NBC is also removed, but now I do not get any broadcast packages??

I read the EMAC documentation three times, but I simply cannot figure out what I am missing, so any pointers is highly appreciated.
