This is allow to kenv hw.cxgbe.nrxq10g=8 ; kldunload if_cxgbe ; kldload if_cxgbe ; /etc/netstart only a few seconds downtime. _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
