Duplicate, NB_SOCKETS already defined, see above.

As you are moving it anyway probably a good time to put portid param in (),
or even make it a static inline function.

Seems like that TODO wasn't done :)
Probably a good thing to add extern for all global vars declarations here,
and keep actual definitions in ipsec-secgw.c.
Same story for:
+struct socket_ctx socket_ctx[NB_SOCKETS];
in ipsec.h
