This of course have to be checked in some hardware documentation for
the correct condition. We already have some workaround (right above
the newly added code) for boards with boardrev>= 0x1250. So my guess
is the code I added applies to some other cards. The board this patch
is supposed to fix is:
board vendor: 14e4
board type: 608
board revision: 1109
board flags: 402201
board flags2: 884
firmware revision: 262032c

So whatever condition we will need it'll likely need to cover above
case (maybe boardrev == 0x1109?).

Well, there is something fishy going on. The brcmsmac code looks like:

if (bfl & BFL_FEM && chip == 4313) {
	if (!(boardrev >= 0x1250 && bfl & BFL_FEM_BT))
		ai_epa_4313war(wlc_hw->sih);
}

However the boardflags above (0x402201) only has BFL_FEM_BT set so this code is never called. I have to ask if !BFL_FEM && BFL_FEM_BT is a valid combination.

Regards,
Arend
