From 04abc0a330327c69dfe1518fb2f5a8b4749b0f37 Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Wed, 27 Mar 2013 19:10:31 -0700 Subject: mwifiex: change default tx/rx win_size for BA setup This patch fixes an issue where RX throughput values observed were substantially lower than TX counterparts for PCIe8897 STA. PCIe8897 supports larger rx_win_size. After changing these values we see big improvement for TX and RX throughput values. Different tx_win_size and rx_win_size are used for AP mode. All BA setup related initialization has been moved to separate function.
