Subject: [PATCH v5 09/14] net: pch_gbe: Use pch_gbe_disable_dma_rx() in pch_gbe_configure_rx()
Date: Sat, 17 Feb 2018 12:10:32 -0800 [thread overview]
Message-ID: <20180217201037.3006-10-paul.burton@mips.com> (raw)
In-Reply-To: <20180217201037.3006-1-paul.burton@mips.com>
The pch_gbe_configure_rx() function open-codes the equivalent of
pch_gbe_disable_dma_rx(). Remove the duplication by moving
pch_gbe_disable_dma_rx(), and pch_gbe_enable_dma_rx() for consistency,
to be defined earlier than pch_gbe_configure_rx() and have
pch_gbe_configure_rx() call pch_gbe_disable_dma_rx() rather than
duplicate its functionality.
