From ae02d41551d6f2a035d3e63ce4415e1b2ba3a7e6 Mon Sep 17 00:00:00 2001 From: Eran Ben Elisha Date: Fri, 12 Feb 2021 14:30:38 -0800 Subject: net/mlx5: Add register layout to support real-time time-stamp Add needed structure layouts and defines for MTUTC (Management UTC) register. MTUTC will be used for cyc2time HW translation. In addition, add cyc2time modify capability bit and init segment HCA real time address. Finally, add capability bits indicating which time-stamping format is supported per SQ and RQ. Add ts_format in the queue's context layout to allow configuration.
