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.")
