Subject: [PATCH net-next 09/15] net: mvpp2: always disable both MACs when disabling a port
Date: Thu, 28 Feb 2019 14:21:22 +0100	[thread overview]
Message-ID: <20190228132128.30154-10-antoine.tenart@bootlin.com> (raw)
In-Reply-To: <20190228132128.30154-1-antoine.tenart@bootlin.com>

This patch modifies the port_disable() helper to always disable both the
GMAC and the XLG MAC when called. At boot time we do not know of a port
was enabled in the firmware/bootloader, and if so what mode was used
(hence which of the two MACs was used).

This also help in implementing a logic where all blocks are disabled
when not used, and only enabled regarding the current mode used on a
given port.
