I was curious if there was a way to use the if_ath.c file in order to change
transmission power on the fly in the middle of a program. This is in if_ath:
ath_hal_setuptxdesc(ah, ds
, pktlen /* packet length */
, hdrlen /* header length */
, atype /* Atheros packet type */
, 0x60 /* txpower XXX */
, txrate, 1+10 /* series 0 rate/tries */
, iswep ? sc->sc_ic.ic_wep_txkey : HAL_TXKEYIX_INVALID
, antenna /* antenna mode */
, flags /* flags */
, ctsrate /* rts/cts rate */
, ctsduration /* rts/cts duration */
);
So I would assume there is a way to do it, although I seem stuck. Do I have
to construct each packet by hand (is this even feasible)? I saw back in
September that Sam Leffler said "per-packet TPC is not working right now",
so I assume that it may have been worked on or at least checked out since
then.
Still no support for TPC. There's a sysctl knob for a global power
setting but nothing per-packet.
