3.13.11.1 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Felix Fietkau <nbd@xxxxxxxxxxx> commit 3b3e0efb5c72c4fc940af50b33626b8a78a907dc upstream. qi->tqi_readyTime is written directly to registers that expect microseconds as unit instead of TU. When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so convert it to microseconds before passing it to ath9k_hw. This should hopefully fix some Tx DMA issues with buffered multicast frames in AP mode. Signed-off-by: Felix Fietkau <nbd@xxxxxxxxxxx> Signed-off-by: John W.
