Hey, I've finally came back to my 14e4:4329 with not working DMA. I
hoped disabling parity will make my DMA work, but this didn't do the
trick.
The card is PCI one with following params:
SSB 2.4
BCM4321
SPROM: 4
PMU: ─
Core rev: 11
PHY: N / 1
Radio: 0x2055 / 4
Some additional details. This is card taken out from Asus WL-500W and
sent to me by Patryk, some Polish Asus owner.
I've put this in my extremely old Acer based on x86_64 CPU, however
running x86 compiled system.
The reference driver does what we do. It reads SSB_TMSHIGH to see if
SSB_TMSHIGH_DMA64 is set. In addition, I do not see any place for a fallback
mechanism such as we have in b43_dma_set_mask(). That might be a good place to
put in the quirk for 14e4:4329.
