Description

[arswitch] begin tidying up the learning and ATU management, introduce ATU APIs.

  • Refactor the initial learning configuration (port learning, address expiry, handling address moving between ports, etc, etc) into a separate HAL routine
  • and ensure that it's consistent between switch chips - the AR8216,8316,724x,9331 SoCs all share the same switch code.
  • .. the AR8327 needs doing - the defaults seem OK for now
  • .. the AR9340 is different but it's also programmed now.
  • Add support for flushing a single port worth of ATU entries
  • Add support for fetching the ATU table from AR8216 and derived chips

Tested:

  • AR9344, Carambola 2

TODO:

  • Further testing on other chips
  • Add AR9340 support
  • Add AR8327 support
