- staging: fsl_ppfe/eth: Disable termination of CRC fwd.
-
- LS1012A MAC PCS block has an erratum that is seen with specific PHY AR803x.
- The issue is triggered by the (spec-compliant) operation of the AR803x PHY
- on the LS1012A-FRWY board.Due to this, good FCS packet is reported as error
- packet by MAC, so for these error packets FCS should be validated and
- discard only real error packets in PFE Rx packet path.
