Author: np Date: Tue Nov 10 02:29:19 2015 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.
