Er, I meant dc_attach. Rilly. Trust me. ;) (<dunce> I think I
initially guessed there from the 'set our mac address' comment without
taking *any* of the surrounding code into context. </dunce>)
I skimmed over a portion of the DM9102A data sheet, saw the SROM layout,
and modified this driver to grab the MAC from that space. It's worked
fine ever since.
(I sent a pr this morning with said patch, and while my mail logs show
the message as having been received as msgID B63E843E3B, it hasn't sho=
wn
up anywhere.)
Thoughts?
