sr: add "set sr encaps hop-limit" command
Default hop-limit for the encapsulating IPv6 header is a compile-time constant. Add ability to specify custom hop-limit, in order to avoid packets being dropped with "hop limit exceeded in transit" response in certain network configurations. Type: feature Signed-off-by: Ignas Bačius <ignas@noia.network> Change-Id: I77f2b35c987cfd31801dc2744d31fb3c1984158f
