step is 60ps. The default value is the neutral setting, so setting
rxc-skew-ps=<0> actually results in -900 picoseconds adjustment.
The KSZ9031 hardware supports a range of skew values from negative to
positive, where the specific range is property dependent. All values
specified in the devicetree are offset by the minimum value so they
can be represented as positive integers in the devicetree since it's
difficult to represent a negative number in the devictree.

Notes:
Note that a previous version of the Micrel ksz9021rl/rn Data Sheet
was missing extended register 106 (transmit data pad skews), and
incorrectly specified the ps per step as 200ps/step instead of
120ps/step. The latest update to this document reflects the latest
revision of the Micrel specification even though usage in the kernel
still reflects that incorrect document.

* to the switch port being completely dead (RX and TX are both not
