I'm trying to port some patches forward to 3.10....
I am trying to find the current channel for a radio. Since
hw.conf.channel no longer exists, what is the best way to
go about this?
Well there's hw.conf.chandef.chan now I think, but that can be NULL and
generic mac80211 code must not use it. There's no single current channel
any more, you want vif->chanctx or so.
From looking at the scanning code (line 542 or so), it appears
local->_oper_chandef.chan
might work?
In 3.9, ath9k_htc was giving me a null channel in the code below:
chanctx_conf = rcu_dereference(sdata->vif.chanctx_conf);
if (chanctx_conf)
channel = chanctx_conf->def.chan;
else
channel = NULL;
I haven't tried that yet in 3.10 or later, so maybe I don't need the
hw.conf.channel in new code anyway.
Thanks,
Ben
