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

xdp-tools: add bpf map path as cmd line argument

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.

Initial list of changes required to build iso
and flash image successfully:
1 softwares require config.guess and config.stub
update with loongarch support
2 no rust build and no suricata which depends on rust
3 comment out python 3.10 lib-dynload and config-3.10-xxxMACHINExxx-linux-gnu
4 lfs/cdrom lfs/Config loongarch seems requiring capital EFI boot image name
to boot properly
5 comment out a few softwares that are not needed for now
iso can be installed to loongarch PC hard drive, but
fail to boot.
flash image can be dd to USB drive, then boot loongarch
PC from USB drive, then dd from USB drive to loongarch
PC hard drive

This patch adds the prosibility to place additional *.config files in /etc/ssh/sshd_config.d/
which will be included and loaded during the daemon startup process.
Because this files will not be overwritten by any update, they can be used to place custom
or other persistent settings.

When we import all static leases, their remark will be used as hostname
(because WTF?) and might be overwritten if the device is not sending any
or even the same hostname.
This patch avoids that static leases will be modified.

This option needs to be configurable since some (braindead) ISPs have
started running broken DHCP servers to be bug-compatible with cheap
broken plastic routers.
By default we keep this option enabled, but it can now be turned off
whenever needed.

It can happen that udev has an event for an interface in the queue that
has already gone away - or even just being renamed.
Then reading the MAC address fails. Because the shell expands the
"$(<...)" statement before running the whole line, the read check is
useless.
Because the code would get too complicated otherwise, I decided to use
cat. Not cool, but this does the job.
