loxilb ebpf program relies on libbpf 0.8
which does not have loongarch64 support.
backported libbpf 1.2.3 loongarch support
to libbpf 0.8
loxilb 0.9.8 now load ebpf program through
libbpf, no external ntc command required, so

Loongarch64 does not support bpf trampoline
and freplace, so we can't use libxdp to attach
multiple XDP program to same network interface.
Loongarch64 supports bpf tail call, so we can still
use xdp-loader to load XDP program, and use bpf tail
call to call each XDP program. now we can tail call
DNS and TLS SNI XDP program on green0 interface
change user space program to take bpf map path as
command line argument so X86 and Loongarch64 can share
same user space program

set CONFIG_ARCH_STRICT_ALIGN=n to enable
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS. this
allows loading BPF program with unaligned memory
access generated by clang, see [0].
this change might cause BPF program fail to load
in loongarch CPU models that require strict aligned
memory access.

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.

no need to compress since other drivers are
not compressed.
had one instance that when system boots up
from the flash image USB drive, and when
setup the network, the driver is not loaded.
it is caused when kernel is rebuilt, yt6801
also need to be rebuilt, but linux-initrd
initramfs is not rebuilt which actually
runs the module dependencies, so linux-initrd
also need to rebuilt together.
