I think so too.

Thanks!  Committed.

No - you mentioned that the environment was there on your version.  Because
the environment checksum happened to have an odd first byte, and the first 6
bytes at that offset are used for the MAC address, my MAC address ended up
as a multicast address.  Easily fixed with:

  printf \\x00\\x11\\x32\\x01\\x95\\x49 > mac-addr.bin

copying the file via tftp, and writing to flash to restore the MAC address.

Still can't get it to boot with only 2 receive descripters.  It seems that
if we fill both descriptors (e.g. one broadcast, one unicast reply), then
it stops receiving.  I checked all the descripter ctl words when we received
a packet, and also on timeout, to check the behaviour.  I will just patch my
skg.c locally to use 8 descriptors.

Thanks,

J
