From 44d6fa90a8fddee49b5749cadbd0add22b1f5559 Mon Sep 17 00:00:00 2001 From: Chun-Yeow Yeoh Date: Fri, 7 Mar 2014 10:19:30 +0200 Subject: [PATCH] ath10k: allow the supported rate change by reassociate peer IBSS mode requires the changing of supported rate. Do this by reassociate the peer. The investigation shows that if move from legacy to HT, the rate control won't work after changing the supported rate. But once changing the supported rate to HT, user can assign the TxRate in HT mode.
