Subject: [PATCH 3.6 1/4] ath9k_hw: do not enable the MIB interrupt in the interrupt mask register
Date: Tue, 7 Aug 2012 15:06:09 +0200 [thread overview]
Message-ID: <1344344772-49459-1-git-send-email-nbd@openwrt.org> (raw)
The interrupt is no longer handling it. While it shouldn't fire (wraparound
is highly unlikely), the consequences would be fatal (interrupt storm).
Disable the interrupt to prevent that from happening.
