From 6ee63f55c7754462a45315ac93027a1df60667c9 Mon Sep 17 00:00:00 2001 From: Senthil Balasubramanian Date: Wed, 10 Nov 2010 05:03:16 -0800 Subject: ath9k_hw: Fix low throughput issue with AR93xx TX underruns were noticed when RTS/CTS preceded aggregates. This issue was noticed in ar93xx family of chipsets only. The workaround involves padding the RTS or CTS length up to the min packet length of 256 bytes required by the hardware by adding delimiters to the fist descriptor of the aggregate.
