Hi, support for ath10k cards was added a while ago to OpenWrt. Unfortunately, the actual 802.11ac support was never added (patches on the mailing lists were just ignored). This is a rather unpleasant situation when trying to get some 11ac test hardware working.
I've picked up the patches and rebased them on top of the current master
branch/trunk.
Just as general information to the state of ath10k, my current test showed
some problems with it:
* Samsung GT-I9300 only got horrible slow connections to an QCA9880 but
an Intel N6205 (using iwlwifi from v3.12) or Samsung S4 worked "fine"
* Adhoc mode doesn't work at all
* TX bitrate information is bogus (iw XXX station dump)
* Crashed relative often on reconfiguration:
Data bus error, epc 87b7a864, ra 87b7a864
* Sometimes adding of station seems to fail:
ath10k: Failed to add peer 5c:0a:5b:4e:6a:c4 for vdev 1 when adding a new
sta: -145
* Adhoc interface + "iw dev wlan0 scan trigger" just crashes the firmware:
[ 296.160000] ath10k: firmware crashed!
[ 296.170000] ath10k: hardware name qca988x hw2.0 version 0x4100016c
[ 296.170000] ath10k: firmware version: 65.467.0.0
* ...
So it is a long way to got but we have to start somewhere.
Kind regards,
Sven
Btw. I have also posted the two patches on github [1] because the second one
is rather large and is a potential candidate for getting rejected by the
mailing list.
