cool - are you a bit of hacker? If so, you should be able to cope with the
request below, and the explaination. If not, or you don't understand the
stuff below, then maybe the driver is not yet ready
for you (no offence intended).

The driver is not very ready (as I have some problems interrupt problems),
but can transmit. Receive is not working - well not even written. If you can


as a module, kldload it and then
    ifconfig bcm0
    ping -c 1
and send me the copious dmesg output I would be very grateful.

The mahcine I am developing on has a problem with interrupts. There is a
problem with RX DMA descriptors that I haven't figured out. Sebastian
sent me a log this morning and he has the same interrupt problem as I do.
