From 3747c3eef6df9bf936fc571ab64122e651db6137 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 8 Apr 2013 00:04:12 +0200 Subject: ath9k: detect more kinds of invalid descriptors If AR_CRCErr, AR_PHYErr, AR_DecryptCRCErr or AR_MichaelErr is indicated in the rx status word, but AR_RxFrameOK is also set, the descriptor contents are typically invalid. This can show up as a warning about invalid MCS rates in a frame. Even with those checks in place, a descriptor with invalid MCS rates can still sometimes make it through to the driver (mostly on older hardware like AR91xx). Detect such errors in the last descriptor of a frame and discard the whole frame if present. Signed-off-by: Felix Fietkau Signed-off-by: John W.
