Subject: [PATCH net 3/4] net: stmmac: selftests: Guard VLAN Perfect test against non supported HW
Date: Tue, 14 Jan 2020 17:09:23 +0100 [thread overview]
Message-ID: <8dd7b44a9daa12301b34c3cb4b393c6d0e4a104a.1579017787.git.Jose.Abreu@synopsys.com> (raw)
In-Reply-To: <cover.1579017787.git.Jose.Abreu@synopsys.com>
In-Reply-To: <cover.1579017787.git.Jose.Abreu@synopsys.com>
When HW does not support perfect filtering the feature will not be
enabled in the net_device. Add a check for this to prevent failures.
Fixes: 1b2250a04c1f ("net: stmmac: selftests: Add tests for VLAN Perfect Filtering")
