Subject: [PATCH net-next 0/3] mlxsw: spectrum: Implement loopback ethtool feature

From: Ido Schimmel <idosch@...lanox.com>

This patchset from Jiri allows users to enable loopback feature for
individual ports using ethtool. The loopback feature is useful for
testing purposes and will also be used by upcoming patchsets to enable
the monitoring of buffer drops.

Patch #1 adds the relevant device register.

Patch #2 Implements support in the driver.

Patch #3 adds a selftest.

  mlxsw: reg: Add Port Physical Loopback Register
  mlxsw: spectrum: Implement loopback ethtool feature
  selftests: Add loopback test
