[Madwifi-devel] disable hw HAL ack for a subset of devices

[Kan C. <ka...@gm...>]

Hi, all:

  I know this is rather strange to do, but I am trying to implement a
some-kind "selective ACK". In other words, the madwfi AP will only ack
a chosen set of devices, but not all the devices. For example, if
there are two devices A and B associates with AP C, I would like to
have AP C only to ack device A only but not B.  I have read Jrj's post
to disable ACKs in HAL
(http://kerneltrap.org/mailarchive/madwifi-devel/2008/4/3/1335084),
but I wonder if this selected ACK can be done as well. Do I have to
implement some sort of soft ACK on the top? How is the timing
constraint (10 us turn-around time).

  If I need to use openHal for this (ath5k), I wonder if it has
supported hostap mode yet?

  Any suggestion would be appreciated. Thanks in advance.

cheers,
