Short description

It would be nice to be able to use eBPF filtering when available with a DynBlockRulesGroup.

Usecase

Take full advantage of the new DynBlockRulesGroup interface in combination with eBPF filtering.

Description

Since the number of entries in an eBPF table is limited the implementation would need to fallback to "regular" rules if the insertion of a new entry fails.
Making sure that eBPF support is fully functional from a program is not easy so I don't think this feature should be enabled by default.
