From f51d3b71d4d3eacfbbc6e2cf3fa197774df5f638 Mon Sep 17 00:00:00 2001 From: Valentin Longchamp Date: Fri, 18 Oct 2013 11:47:21 +0200 Subject: [PATCH] net/fman: add a fm_enable_port function This can be useful if one wants to disable an interface in u-boot because u-boot should not manage it but then later reenable it for FDT fixing or if the kernel uses this interface.
