URL: https://svnweb.freebsd.org/changeset/base/366469
Log:
Clear the dmesg buffer to prevent rotating causes issues
This is a workaround for the current continuously failing test case
sys.kern.sonewconn_overflow.sonewconn_overflow_01
The side effect is the dmesg buffer got cleared and may effect other tests
depends on dmesg output running in parallel. The better solution would be
tailing the log file like /var/log/debug.log
