4.0-RELEASE, 4.0-STABLE, 5.0-CURRENT
PC with RISCom/N2(isa or pci) and Leased Line connection
pseudo-device sppp
device sr
>Description:
write to rc.conf:
network_interfaces="sr0 ..."
ifconfig_sr0="inet 192.168.1.1 192.168.1.2 netmask 0xfffffffc link2 debug up"
but then,
ifconfig sr0 shows without LINK2 and DEBUB
So, CISCO_HDLC connection is not done.
>How-To-Repeat:
>Fix:
firsttime sr_ioctl() calls sppp_attach,
sppp_attach destroys ifp->if_flags
So, sr_ioctl ignores LINK2 and DEBUG flags
my temporary patch is here. (if_spppsubr.c:sr_attach())
