[PATCH net-next V2 3/4] net/mlx5e: Add HW timestamping (TS) support

From: Eran Ben Elisha Add support for enable/disable HW timestamping for incoming and/or outgoing packets. To enable/disable HW timestamping appropriate ioctl should be used. Currently HWTSTAMP_FILTER_ALL/NONE and HWTSAMP_TX_ON/OFF only are supported. Make all relevant

[PATCH net-next V2 4/4] net/mlx5e: Add PTP Hardware Clock (PHC) support

From: Eran Ben Elisha Add a PHC support to the mlx5_en driver. Use reader/writer spinlocks to protect the timecounter since every packet received needs to call timecounter_cycle2time() when timestamping is enabled. This can become a performance bottleneck with RSS and
