> define FEC_ENET_ENABLE_TXC_DELAY to enable the delay on TXC line on
> the MAC. This has to be done in order to meet RGMII specs.
> According to RGMII specs the clock should get delayed so the edges of
> the clock are preferrably in the middle of the edges of data-lines so
> they can be sampled properly.
> Our PHY expects the MAC to delay TXC line, as it is also written
> in the spec. This patch makes sure the TXC delay on the FEC is enabled
