[PATCH net-next 0/2] net: dsa: mxl862xx: MDIO bus integrity and optimization

Posted by Daniel Golle 1 week, 6 days ago

The MxL862xx firmware offers opt-in CRC validation on the MDIO/MMD
command interface to guard against bit errors on the bus.
The driver has not used this until now.

This series enables CRC protection on both the command registers (CRC-6)
and data payloads (CRC-16), and reduces MDIO bus traffic by bulk-zeroing
registers instead of writing zero-valued words individually.

Daniel Golle (2):
  net: dsa: mxl862xx: add CRC for MDIO communication
  net: dsa: mxl862xx: use RST_DATA to skip writing zero words
