Subject: [PATCH net 7/8] net: stmmac: xgmac: Disable the Timestamp interrupt by default
Date: Fri, 27 Sep 2019 09:48:55 +0200	[thread overview]
Message-ID: <5060574f7023e1ae13e429fcf86e373c6a79f965.1569569778.git.Jose.Abreu@synopsys.com> (raw)
In-Reply-To: <cover.1569569778.git.Jose.Abreu@synopsys.com>
In-Reply-To: <cover.1569569778.git.Jose.Abreu@synopsys.com>

We don't use it anyway as XGMAC only supports polling for timestamp (in
current SW implementation). This greatly reduces the system load by
reducing the number of interrupts.

Fixes: 2142754f8b9c ("net: stmmac: Add MAC related callbacks for XGMAC2")
