Subject: [PATCH 1/1] net: designware: eqos: stop DMA on halt
Date: Mon, 11 Nov 2019 10:56:07 +0100 [thread overview]
Message-ID: <20191111095607.1813-2-ahmad@a3f.at> (raw)
In-Reply-To: <20191111095607.1813-1-ahmad@a3f.at>
designware_eqos.c contains an eqos_stop implementation to stop the NIC
when halting the interface. Unfortunately it wasn't used leading to
memory corruption on boot, possibly due to DMA. Fix this.
