When XDP DDoS syncookie program is attached
to red0 interface, green network client internet
connection to website like gmail/youtube... failed.
it is because these sites does not have IP DF flag
set for each tcp packet, and syncookie_xdp program
would drop these packets when they arrived at red0
interface.

suricata XDP support requires xdp-tools with
libbpf 1.4 to resolve stack smash issue.
also workaround memlock operation not permitted
by running suricata as root since load/attach
XDP program requires root privilige anyway.
see: https://github.com/vincentmli/BPFire/issues/54
Usage scenario:
since suricata IPS XDP capture mode works as
layer 2 bridge, BPFire netfilter firewall, NAT
IP route will be bypassed. no IP address should
be assigned to red0 and green0 interface.
172.16.1.0/24 inline 172.16.1.0/24
red network<-->red0(xdp)<-->green0(xdp)<-->green network
we can run setup command to assign IP/Mask 0.0.0.0/0.0.0.0
to red0 and green0, then reboot BPFire, BPFire DHCP
will stops working after reboot. green network client
can get DHCP IP from upstream dhcp server.
start suricata manually
suricata -c /etc/suricata/suricata-xdp.yaml --af-packet
xdp_filter.bpf program will be attached to red0 and gree0
interface
not sure if we should add GUI for suricata XDP capture mode
since this is not common use case.

add the missing config/cfgroot/xdpdns-settings file
and use ENABLE_DNSBLOCK=on by default, so XDP DNS
Blocklist is enabled by default.
also add domainfile so when BPFire reboot first time
and when xdpdns init startup, it will not complain
missing domainfile

run xdp_dns in xdpdns init script to populate

either xdpdns restart or bpfire reboot, the domain_denylist
is restored with domain blocklist

if XDP DNS is enabled, and BPFire reboot, XDP

Lunatik sni filter currently does not work
for BPFire when chrome browser is used due to
clienthello > 1500 bytes, XDP TLS/SSL has
the same issue, to block domain access, it
appears XDP DNS domain blocking works more
reliable than SNI, so if there is need to block
chrome browser for some domain, use XDP DNS
domain blocking as mitigation.

Add the missing serial linux command so the
flash image can be converted to qcow2, the
bpfire qcow2 image can be deployed in KVM
virtual environment through serial console
installation.
for exmaple:
virsh define BPFire-VM.xml
virsh start BPFire-VM
virsh console BPFire-VM
we will have serial console access to BPFire
VM and the installation will start.
