I already committed some performance fixes in OpenWrt that bring UDP performance over a WDS link between an AR9344+AR9380 (Atheros DB120) and an AR7242+AR9380 (TP-Link TL-WR2543ND) up to about 310-320 Mbit/s, when doing Tx on the DB120 side. Reverse direction is slower, because AR7242 isn't as powerful as the AR9344. These fixes do not touch ath9k, I only tweaked the network stack to avoid redundant copying/reallocation of skb data. - Felix
