Author: hselasky Date: Wed May 8 10:39:25 2019 New Revision: 347271 URL: https://svnweb.freebsd.org/changeset/base/347271 Log: Implement PCAM, MCAM access register commands in mlx5core. Introduced registers will expose capabilities of new registers and features related to port/management. Driver will query MCAM and PCAM in order to avoid failing on old firmwares with lack of support.
