Ok, tried that, no change that I can see.

Dumping out the CAMs on the live system with gdb, the first two appear
to contain "something". If read as little-endian int16's, the first is
the local MAC address (08:00:07:2e:2f:74). The second is
01:00:5e:00:ff:00 which I don't recognise. What endian are these
supposed to be in? Also, scd_camenable appears to contain rubbish (in
little-endian, it is 0x6ddb). The reason I believe it to be rubbish is
that the same pattern appears in the remaining cda_entry's.

I might take a look at this more over the weekend.

For reference:
scd_cam = {
{cda_entry = 0, cda_addr0 = 8, cda_addr1 = 11783, cda_addr2 = 29743},
{cda_entry = 1, cda_addr0 = 1, cda_addr1 = 94, cda_addr2 = 256},
{cda_entry = 3, cda_addr0 = 28086, cda_addr1 = 56173, cda_addr2 = 46811},
{cda_entry = 28086, cda_addr0 = 56173, cda_addr1 = 46811, cda_addr2 = 28086},
{cda_entry = 56173, cda_addr0 = 46811, cda_addr1 = 28086, cda_addr2 = 56173},
{cda_entry = 46811, cda_addr0 = 28086, cda_addr1 = 56173, cda_addr2 = 46811},
{cda_entry = 28086, cda_addr0 = 56173, cda_addr1 = 46811, cda_addr2 = 28086},
{cda_entry = 56173, cda_addr0 = 46811, cda_addr1 = 28086, cda_addr2 = 56173},
{cda_entry = 46811, cda_addr0 = 28086, cda_addr1 = 56173, cda_addr2 = 46811},
