From 9637e516d16a58b13f6098cfe899e22963132be3 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 10 May 2010 15:26:27 -0400 Subject: [PATCH] ath5k: drop warning on jumbo frames Jumbo frames are not supported, and if they are seen it is likely a bogus frame so just silently discard them instead of warning on them all time. Also, instead of dropping them immediately though move the check *after* we check for all sort of frame errors. This should enable us to discard these frames if the hardware picks other bogus items first. Lets see if we still get those jumbo counters increasing still with this. Jumbo frames would happen if we tell hardware we can support a small 802.11 chunks of DMA'd frame, hardware would split RX'd frames into parts and we'd have to reconstruct them in software. This is done with USB due to the bulk size but with ath5k we already provide a good limit to hardware and this should not be happening. This is reported quite often and if it fills the logs then this needs to be addressed and to avoid spurious reports. Cc: stable@kernel.org Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
