In my case I have following problem. sky2_set_multicast() sets registers
GM_MC_ADDR_H[1-4] correctly to:
0000 0800 0001 0410
However, when adapter gets link and sky2_link_up() is called, the values
are for some reason different:
0000 0800 0016 0410

Rather than papering over the problem, it would be better to
trace back what is setting those registers and fix that code.

Yes, I did that. No code at sky2.[ch] is writing to this registers other
than sky2_set_multicast() and sky2_gmac_reset() (I hooked on sky2_write*()).
So I strongly believe this is a HW issue (maybe only issue of my revision
"Yukon-2 EC chip revision 2")

I would like to check the registers as soon as I'm back in my office next week and report my findings.
Could you also please check the hint from Stephen?
