From mboxrd@z Thu Jan 1 00:00:00 1970 From: troy.kisky@boundarydevices.com (Troy Kisky) Date: Thu, 28 Jan 2016 14:25:38 -0700 Subject: [PATCH net-next 14/40] net: fec: don't clear all rx queue bits when just one is being checked In-Reply-To: <1454016364-30985-1-git-send-email-troy.kisky@boundarydevices.com> References: <1454016364-30985-1-git-send-email-troy.kisky@boundarydevices.com> Message-ID: <1454016364-30985-15-git-send-email-troy.kisky@boundarydevices.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org FEC_ENET_RXF is 3 separate bits, we only check one queue at a time. So, when the last queue is being checked, it is bad to remove the interrupt on the 1st queue. Also, since this is now done in the napi routine and not the interrupt, it is not needed.
