From b0a3344834fcaf30e472ccc661c8842281453402 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Thu, 15 Apr 2010 17:39:39 -0400 Subject: ath9k: add LDPC support LDPC is enabled by the rate control if the its determined that the target peer supports LDPC. We would have already intersected the HT capabilities so if our peer supports LDPC so do we. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
