Author: yongari Date: Mon Nov 15 00:06:19 2010 New Revision: 215329 URL: http://svn.freebsd.org/changeset/base/215329 Log: Add flow control for all re(4) controllers. re(4) controllers do not provide any MAC configuration interface for resolved flow control parameters. There is even no register that configures water mark which will control generation of pause frames. However enabling flow control surely enhanced performance a lot.
