| H A D | if_ath.c | diff 220324 Mon Apr 04 13:03:14 MDT 2011 adrian Add a HAL capability bit for supporting self-linked RX descriptors and disable it for the 11n chipsets. From the ath9k source: == 11N: we can no longer afford to self link the last descriptor. MAC acknowledges BA status as long as it copies frames to host buffer (or rx fifo). This can incorrectly acknowledge packets to a sender if last desc is self-linked. == Since this is useful for pre-AR5416 chips that communicate PHY errors via error frames rather than by on-chip counters, leave the support in there, but disable it for AR5416 and later. |
