This series ports the existing NFS code so that it can be used with both
the legacy network code and also with LWIP.
Firstly some legacy network code, mostly variables, is moved into common
files so that it is accessible to LWIP.
Secondly the NFS code is refactored so that the parts that are not
specific to the network code can be shared with both network
implementations.
Finally the LWIP specific parts needed to interface the NFS shared code
to that network stack are added and enabled.

Best regards,
Thank you for looking into the LWIP port.
We lack an NFS server in our Gitlab CI to run the NFS test.
For HTTP we are running
python3 -m http.server 80 --directory "${UBOOT_TRAVIS_BUILD_DIR}"
in .gitlab-ci.yml.
We should do something similar for NFS.
There is a userspace NFS server available
at https://github.com/unfs3/unfs3.
This worked on my workstation:
cat > exports << EOF
/home/ubuntu
EOF
./unfsd -e `pwd`/exports -u -n 4096 -m 4096
sudo mount -t nfs \
-o port=4096,mountport=4096,mountvers=3,nolock \
localhost:/home/ubuntu /mnt
Now in /mnt I could see the /home/ubuntu file-system.
With LWIP we should think about enabling tcp for NFS.
Best regards
Heinrich
