commit 38ae92d "fec: Add support for reading RMON registers" causes the imx6Q to crash. This fixes it by only enabling the RMON registers, the registers are already cleared by the MAC being reset. Signed-off-by: Jim Baxter <redacted> --- Change v1 to v2 Removed per processor change and just set bit 31 to 0. Change v2 to v3 Fixed comment to describe operation correctly. drivers/net/ethernet/freescale/fec_main.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-)
