FreeBSD has no such framework in mii layer yet so it's completely up to driver. em(4) handles flow-control in driver so it can handle flow-control. > Can FreeBSD 6.x or 7.x handle PAUSE frames, at least receiving them ? > Receiving pause frames have no problem on any driver but most drivers does not respond with the pause frames. AFAIK marius@ has a flow-control patch so I guess FreeBSD will have generic flow-control capability which will make it available on all ethernet drivers with minor modification. > Thanks for any pointer! > -- Regards, Pyun YongHyeon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
