CPSW: Host to Ethernet Timestamp Accuracy Issue
When a packet is sent from the Host to Ethernet with a timestamp to be generated on Ethernet egress, a packet length with 0xD5 in the lower 8-bits results in a timestamp error.
Using timestamp for PTP messages should not be impacted as the PTP messages are usually much shorter than 0xD5 packet length.
Ethernet timestamp should be enabled only for PTP messages on Host Tx.
