svn commit: r290633 - head/sys/dev/cxgbe/firmware

[Navdeep Parhar]

Author: np

New Revision: 290633
URL: https://svnweb.freebsd.org/changeset/base/290633

Log:
  cxgbe/t4_tom: add a knob to the default configuration file to tune
  the TOE for LAN operation.  It is possible to set this to other values
  (cluster for networks with little loss and really tight RTTs, and wan
  for relatively large RTTs and/or lossy networks) depending on the
  environment in which the TOE is being used.
  
  None of this affects plain NIC operation in any way.
