em(4) supports zero copy for Tx side. zero copy for receiver side requires header splitting assistance from hardware which is not available in em(4). I guess ti(4) on Tigon II would be the only driver that supports header splitting. However it seems newer Intel NICs and Sun Cassini+ seems to have header splitting feature. Jack Vogel, maintainer of em(4), may have more information for header splitting support on em(4).(CCed) > thx > > > On Fri, Nov 02, 2007 at 09:39:19AM +0700, binto wrote: > > > I try to compile MYKERNEL to set zero_copy & tigon driver in my machine > > > with: > > > > > > device ti > > > options TI_PRIVATE_JUMBOS > > > options TI_JUMBO_HDRSPLIT > > > > > > but got: > > > #error "options TI_JUMBO_HDRSPLIT and TI_PRIVATE_JUMBOS are mutually > > > exclusive" > > > > > > what's up....? > > > > > > > %vi +/TI_JUMBO_HDRSPLIT /usr/src/sys/conf/NOTES > > > > -- > > Regards, > > Pyun YongHyeon > > > > -- Regards, Pyun YongHyeon _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
