I have wound a little bug in ifup-ipx script.
It dos not configure 802.2 and 802.3 frames.
All to do for correcting this problem is to replace line:

/usr/bin/ipx_interface add $1 $primary $frametype \
 $(eval echo $(echo \$`echo IPXNETNUM_$frametype`))

with this 2 lines:

dframetype=`echo $frametype | sed s/_/./`
/usr/bin/ipx_interface add $1 $primary $dframetype \
 $(eval echo $(echo \$`echo IPXNETNUM_$frametype`))

Best regards,
