Subject: [RFC net-next v2 13/14] net: stmmac: dwmac1000: Clear unused address entries
Date: Tue, 14 May 2019 17:45:35 +0200 [thread overview]
Message-ID: <2f3b629b1f41997f804441f90d8a25f5d5e9f797.1557848472.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1557848472.git.joabreu@synopsys.com>
In-Reply-To: <cover.1557848472.git.joabreu@synopsys.com>
In case we don't use a given address entry we need to clear it because
it could contain previous values that are no longer valid.
Found out while running stmmac selftests.
