Actually seems the pcap is a disaster on Linux host, with stable version doesn't work, with git version at first ping from guest machine give a crash
86Box[23929]: segfault at 3c8 ip 0000000000655468 sp 00007f18317fd940 error 4 in 86Box[426000+40e000]
Slirp network seem's to works.
So ATM I consider the pcap networking bugged on Linux hosts.
p.s=the old SVr4 system is perfectly emulated by qemu
qemu-system-i386 -m 16 -hda unix.img -fda boot.img
but qemu don't support the wd8003 isa card.
EDIT: a workaround/solution found.
Instead of use pcap or slirp use vde.
We need a tap interface, personally I use this script
#!/bin/sh
# Exit at first error
set -e
# Run this as root
if [ $UID != "0" ]
then
echo "Run this script as root"
exit 1
fi
# Increment tap device number
TAP=`ip link show type tun|grep tap|awk '{print $2}'|cut -d : -f 1|cut -c 4|tail -1`
let "TAP=TAP+1"
TAPDEV=tap${TAP}
# Other vars
USER=yourname
BRIDGE=br0
# Create tap for user
ip tuntap add dev $TAPDEV mode tap user $USER
ip link set $TAPDEV up promisc on
ip link set $TAPDEV master $BRIDGE
echo "I have created $TAPDEV for user $USER, using bridge $BRIDGE"
echo "To remove it use command ip link delete $TAPDEV as root"
Then create the switch AS ROOT (as normal user can create the switch..but when you start the 86box machine it will not connect to the switch!)
sudo vde_switch --mode 666 --numports 8 --tap tap1 --mgmt /tmp/vde.manag --mgmtmode 666 -s /tmp/vde.switch --daemon
Then we start the 86Box
After that control the vde switch, must report two ports (the tap1 and the 86box program)
vdeterm /tmp/vde.manag
VDE switch V.2.3.2

Success
Tap1 must configured with ip class of bridge, for example if br0 has 192.168.0.1/24 ip tap1 must have 192.168.0.*/24 and same thing for the virtual machine (for example:
br0 192.168.0.1
tap1 192.168.0.2
vm 192.168.0.3
Finally the results!

For the first time I see on my pc a telnet on old svr4 Unix without using slirp and other slow solutions!

Trying 192.168.0.91...
