--------------------------------
commit 953b0dcbe2e3f7bee98cc3bca2ec82c8298e9c16 upstream.
Commit bf3504cea7d7e ("net: dsa: mv88e6xxx: Add 6390 family PCS registers to ethtool -d") added support for dumping SerDes PCS registers via ethtool -d for Peridot.
The same implementation is also valid for Topaz, but was not enabled at the time.
