New Revision: 330040
URL: https://svnweb.freebsd.org/changeset/base/330040

Log:
  Fetch TLS key parameters from the firmware.
  
  The parameters describe how much of the adapter's memory is reserved for
  storing TLS keys.  The 'meminfo' sysctl now lists this region of adapter
  memory as 'TLS keys' if present.
