# Sometimes there is a need to fine tune the delays. Often the MAC or
# PHY can perform this fine tuning. In the MAC node, the Device Tree
# properties 'rx-internal-delay-ps' and 'tx-internal-delay-ps' should
# be used to indicate fine tuning performed by the MAC. The values
# expected here are small. A value of 2000ps, i.e 2ns, and a phy-mode
# of 'rgmii' will not be accepted by Reviewers.
