net: fec: Add possibility to enable TXC delay
This patch enables the possibility to set FEC_ENET_ENABLE_TXC_DELAY or FEC_ENET_ENABLE_RXC_DELAY so one can via a define enable the RXC or TXC delay in the MAC. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com> Reviewed-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>
