[PATCH net-next 0/4][pull request] 100GbE Intel Wired LAN Driver Updates 2021-10-12

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

The following are changes since commit 177c92353be935db555d0d08729e871145ec698c:
  ethernet: tulip: avoid duplicate variable name on sparc

Maciej Machnikowski (4):
  ice: Refactor ice_aqc_link_topo_addr
  ice: Implement functions for reading and setting GPIO pins
  ice: Add support for SMA control multiplexer
  ice: Implement support for SMA and U.FL on E810-T
