R: R: Link can't get estabilished over RB911AC boards

[Alessandro Bolletta]

Ok Ben, thanks for you infos.

Just for curiosity: do you think that ath10k could be better in performances than official QCA reference drivers (the same used in proprietary distros as RouterOS, for example)?

4.0 is most stable currently, though the last few days I've been committing a lot of barely tested code.  Will test this better shortly.

And, sorry, but I don't have time right now to help with making this work with OpenWrt.  At the least, it is liable to not be trivial.  Search the list for 'CT' + 'OpenWRT' an you may find some help...others have posted patch-sets for OpenWRT that includes at least many of my patches.


Thanks,
Ben
