[PATCH net 1/1] qed: Fix timestamping issue for L2 unicast ptp packets.

[Sudarsana Reddy Kalluru]

commit cedeac9df4b8 ("qed: Add support for Timestamping the unicast
PTP packets.") handles the timestamping of L4 ptp packets only.
This patch adds driver changes to detect/timestamp both L2/L4 unicast
PTP packets.

Fixes: cedeac9df4b8 ("qed: Add support for Timestamping the unicast PTP packets.")
