[PATCH net-next v2 0/4][pull request] 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)

The following are changes since commit 9974cb5c879048f5144d0660c4932d98176213c4:
  net: delete redundant function declaration
