Subject: [net-next 03/12] net/mlx5e: Add PTP-RX statistics
From: Aya Levin <ayal@...dia.com>
Like PTP-TX, once the PTP-RX is opened, corresponding statistics appear.
Add indication that PTP-RX was ever opened: rx_ptp_opened. If any of the
PTP RX or TX were opened, display the PTP channel's statistics.
