[PATCH-next v2 7/8] lnst.Recipes.ENRT.BaseEnrtRecipe: add {udp,sctp}-specific checks

From: Christos Sfakianakis <csfakian(a)redhat.com&gt; Add checks related to UDP/SCTP that are present in the old recipes. In particular, skip ('gro', 'off') offload setting with UDP perf tests. Also, allow only 'gso' option to be set to 'off' with SCTP. Finally, make sure SCTP will go out through the test interfaces only. v2: Skip offload settings which contain 'off' values unless ('gso', 'off') is also contained in them when using SCTP.
