From 3a73e49caa75928149ea54f570f8afb5f6f4774d Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Tue, 3 Jan 2012 11:59:30 +0000 Subject: [PATCH] gianfar: Reject out-of-range RX NFC locations MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently the driver only uses location values to maintain an ordered list of filters. Make it reject location values >= MAX_FILER_IDX passed to the ETHTOOL_SRXCLSRLINS command, consistent with the range it reports for the ETHTOOL_GRXCLSRLALL command.
