Subject: [21/78] ath9k: remove support for the FIF_PROMISC_IN_BSS filter flag
Date: Mon, 21 Mar 2011 16:01:37 -0700 [thread overview]
Message-ID: <20110321230323.829763534@clark.kroah.org> (raw)
In-Reply-To: <20110321230346.GA14681@kroah.com>
2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------
From: Felix Fietkau <nbd@openwrt.org>
commit 2e286947f1294239527c11f9f466ddce6466455b upstream.
The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad
and covers even frames with PHY errors. When this flag is enabled, this message
shows up frequently during scanning or hardware resets:
ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
Since promiscuous mode is usually not particularly useful, yet enabled by
default by bridging (either used normally in 4-addr mode, or with hacks
for various virtualization software), we should sacrifice it for better
reliability during normal operation.
This patch leaves it enabled if there are active monitor mode interfaces, since
it's very useful for debugging.
