That looks ok.

First I was puzzled, because I checked the if_sk.c source again, and saw
that it is not using RXOK, but checks XM_RXSTAT_ERRFRAME.

So I thought for a moment that we have to use the XMAC II status definitions
instead, while I was using RXOK from the Yukon status word, which in the
kernel is only used by the msk(4) Yukon2 driver.

Our NIC is a Marvell Yukon-Light. And it obvisouly uses the Yukon status
layout (otherwise your debug output would be nonsense). This might be a
bug in if_sk.c, which fortunately had not much effect yet.

Hmm. But can you confirm that be packets are sent by your DHCP server?
I would look into the log of the server if it had received a valid DHCP
request. Maybe you have just a configuration problem in dhcpd.conf. When
you are sure the server accepted the NAS request, look out if it sends a
packet directed to it. When there is no packet it cannot receive anything.

I hope the solution is easier, as it already works with Oscar's 407e. :)
