Message-ID: <1413361531-9182-4-git-send-email-peppe.cavallaro@st.com> Date: Wed, 15 Oct 2014 10:25:31 +0200 From: Giuseppe Cavallaro <peppe.cavallaro@...com> To: <netdev@...r.kernel.org> Cc: Giuseppe Cavallaro <peppe.cavallaro@...com> Subject: [net-next.git 3/3] stmmac: remove BUS_MODE_DA This is a very old and often unused option to configure a bit in a register inside the DMA. This support should not stay under Koption and also it is obsolete and should be extended for new chips. This will be do later maybe via device-tree parameters. Also no performance impact when remove this setting on STi platforms.
