From 54ac218ae676931813169e0ca074aca2e4adee38 Mon Sep 17 00:00:00 2001 From: Herton Ronaldo Krzesinski Date: Thu, 13 Nov 2008 10:39:14 -0500 Subject: [PATCH] rtl8187: fix 8187B throughput regression Hin-Tak Leung reported that after the change "rtl8187: add short slot handling for 8187B" his RTL8187B started to give low throughput on network transfers. Turns out that the SIFS setting used isn't ok, it doesn't look to be the real aSIFSTime, using the "magical" 0x22 value like on other 818x variants as the vendor does too fixes the issue.
