It will do so by storing struct\nip_tunnel_parm with previous configuration, and comparing that to the\nnew version.\n\nTo facilitate these comparisons, extract the code that operates on\nstruct ip_tunnel_parm from the existing accessor functions, and make\nthose a thin wrapper that extracts tunnel parameters and dispatches.\n\nSigned-off-by: Petr Machata <petrm@mellanox.com>\nReviewed-by:
