You need to add
struct ip6t_srh_v1 {
/* copy of struct ip6t_srh here */
/* new fields go here */
};
Look at xt_conntrack.c, conntrack_mt_reg[] for an example of
multi-revision match.
You can probably re-origanise code to avoid too much duplication.
See 5a786232eb69a1f870ddc0cfd69d5bdef241a2ea in nf.git for an example,
it makes v0 into a v1 struct at runtime and re-uses new v1 code
for old v0.
