====================
100GbE Intel Wired LAN Driver Updates 2021-10-14

Maciej Machnikowski says:

Extend the driver implementation to support PTP pins on E810-T and
derivative devices.

E810-T adapters are equipped with:
- 2 external bidirectional SMA connectors
- 1 internal TX U.FL shared with SMA1
- 1 internal RX U.FL shared with SMA2

The SMA and U.FL configuration is controlled by the external
multiplexer.

E810-T Derivatives are equipped with:
- 2 1PPS outputs on SDP20 and SDP22
- 2 1PPS inputs on SDP21 and SDP23
---
v2:
- Remove defensive programming check and simplify return statement
  (Patch 3)
- Remove unnecessary parentheses (Patch 4)
====================
