H A D | en_clock.c | ad7d4eae Tue Dec 31 11:39:39 CST 2013 Shawn Bohrer <sbohrer@rgmadvisors.com> mlx4_en: Add PTP hardware clock
This adds a PHC to the mlx4_en driver. We 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 multiple receive queues if normal spinlocks are used.
This driver has been tested with both Documentation/ptp/testptp and the linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox ConnectX-3 card.
