Subject: [RFC 11/34] ath9k_htc: Fix RX length check
Date: Mon, 7 Mar 2011 07:43:47 +0530 [thread overview]
Message-ID: <19828.16219.455263.765424@gargle.gargle.HOWL> (raw)
From: Sujith Manoharan <Sujith.Manoharan@atheros.com>
The length of the received SKB could be equal to
HTC_RX_FRAME_HEADER_SIZE in case of packets with phy/crc errors,
in which case they are dropped without being processed.
Fix this check so that the error counters are updated correctly.
