Author: hselasky Date: Thu May 16 17:30:20 2019 New Revision: 347821 URL: https://svnweb.freebsd.org/changeset/base/347821 Log: MFC r347271: 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.
