I find it hard to believe that after numerous attempts to update the ticket in question (12720) and having mailed the group thrice, that there isn't a single response to the aforementioned issue of half bandwidth. Is there no one with ath9k and relayd expertise ? I'm sure some of the more recent ath10k developments have been fruitful and will benefit the community, just as a fix for this issue would benefit some ath9k/relayd users.
If I had enough driver development expertise I would fix it myself. Please do not take treat this response as a rant, as I am all very thankful for being able to use OpenWrt on my devices. However, this half bandwidth issue is a bit of a niggle that I'd like to eliminate. If anyone can chime in with something helpful it would be "greatly" appreciated.
