New Revision: 290650
URL: https://svnweb.freebsd.org/changeset/base/290650

Log:
  Add mlx5 and mlx5en driver(s) for ConnectX-4 and ConnectX-4LX cards
  from Mellanox Technologies. The current driver supports ethernet
  speeds up to and including 100 GBit/s. Infiniband support will be
  done later.
  
  The code added is not compiled by default, which will be done by a
  separate commit.
