Subject: [PATCH 5.5 341/367] qed: Fix timestamping issue for L2 unicast ptp packets.

From: Sudarsana Reddy Kalluru <skalluru@...vell.com>

[ Upstream commit 0202d293c2faecba791ba4afc5aec086249c393d ]

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.")
