New Revision: 347272
URL: https://svnweb.freebsd.org/changeset/base/347272
Log:
Query and cache PCAM, MCAM registers on initialization in mlx5core.
On load_one, we now cache our capabilities registers internally, similar
to QUERY_HCA_CAP. Capabilities can later be queried using macros
introduced in this patch.
