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.
