From 6163a3735aad19bdb8d02b3362d3a2d7d2eb78d5 Mon Sep 17 00:00:00 2001 From: Shanyu Zhao Date: Fri, 12 Nov 2010 13:48:13 -0800 Subject: [PATCH] iwlagn: check change before commit RXON cmd When setting rxon chain and filter, no need to commit RXON when the chain flag is not changed. This reduces the number of RXON commands we send down to uCode.
