Subject: [PATCH 08/10] ath5k: update phy errors codes
Date: Thu, 25 Mar 2010 14:49:42 +0900	[thread overview]
Message-ID: <20100325054942.10697.65242.stgit@tt-desk> (raw)
In-Reply-To: <20100325054603.10697.48915.stgit@tt-desk>

Update PHY error codes from the HAL, and keep them in statistics for debugging
via the 'frameerrors' file. This will also be used by ANI.
