I recently came across the documentation provided at
http://www.bsd-dk.dk/archives/2001/Mar/0027.html
for implementing the Netgraph Fast-Channel kernel module on FreeBSD
systems it works great. One thing that I have not been able to figure
out is how to change the mtu on the pseudo device to anything greater
than 1500(I want mtu 9000). If I do
#ifconfig fec0 mtu 1000 (this works if its any value less than 1500)
but, if I do
#ifconfig fec0 mtu 9000 (I get the following: " ifconfig: ioctl (set
mtu): Invalid argument ")
I also tried changing the "NG_FEC_MTU_Default 1500" line in the
ng_fec.h file to
NG_FEC_MTU_Default 9000
and then do a build/install new kernel and build/install world. Still
have no success. I you have any suggestions I would greatly appreciate
it.
HERE IS MY ENTIRE SCRIPT:
#! /bin/sh
echo "load module";
cd /usr/src/sys/modules/netgraph/fec/
kldload /usr/src/sys/modules/netgraph/fec/ng_fec.ko
echo "kldstat results";
kldstat
echo "create psuedo fec interfaces";
ngctl mkpeer fec dummy fec
echo "bind physical interfaces to pseudo devices";
ngctl msg fec0: add_iface '"em0"'
ngctl msg fec0: add_iface '"em1"'
echo "set capture mode for each pseudo interface";
ngctl msg fec0: set_mode_inet
echo "set all physical and pseudo interfaces to promiscuous mode";
ifconfig fec0 promisc
ifconfig em0 promisc
ifconfig em1 promisc
echo "bring up pseudos";
ifconfig fec0 up
