AP mode support requirements for iwlagn driver

AP mode support requirements for iwlagn driver

[Milan Plzik]

  Hello,

  what are the exact requirements for AP mode support in iwlagn driver?
Is there any change neccessary in card's firmware, or the only missing
code is in mac80211/iwlagn itself? Also, there was sort-of support for
AP, but it was disabled in later versions -- what were the exact
problems with this implementation?

  Best regards,
	Milan Plzik

One major issue was getting multicast frames out at the right time, but
also look at

  Ok, so from what I understand to get AP mode fully working, firmware
has to adjust TSF -- this seems to be what TX_CMD_FLG_TSF_MSK does;
everything other should be manageable by software.=20

  Btw, the URL unfortunately doesn't mention anything about multicast
frames;  if there something describing this more in detail?
