[OpenWrt-Devel] Ath10k mesh with OpenWRT question

At some point I was able to get IBSS running with an ath10k radio (QCA988X)
using firmware-2.bin_999.999.0.636 [1]. I couldn't test it thoroughly, but
it ran for some days in a production BMX6 mesh. I also tried Ben Greear's
CT firmware, with no success.

If you are starting a network from scratch, however, go for 802.11s instead
of IBSS, as Sven said.

Kind regards,
