The DEB packages shouldn't include FRR support. These may be leftovers
from old "edge" releases. I will delete it.

I have disabled it some time ago:
https://github.com/DPDK/grout/commit/0f0e023bb5c07490b625ba1447a3c9e06df0a961

It was too complicated to manually build the FRR DEB packages.

No, we only support FRR 10.5+ because the grout dplane plugin needs
to be compiled out-of-tree.

This is a fairly recent addition in FRR and the upstream DEB repo does
not even include an frr-headers package.

We have updated the Fedora RPM to install these headers but the DEB
package does not have this change.

https://src.fedoraproject.org/rpms/frr/blob/rawhide/f/frr.spec#_99

We need to do some lobbying both upstream (FRR) and downstream (Debian)
so that they enable out-of-tree plugin support.

In the meantime, we could work on packaging an FRR DEB package for grout
usage.
