- Add encapmtx to protect ip_encap.c global variables (encapsulation list). - Unifdef #ifdef 0 pieces of encap_init() which was (and now really is) basically a no-op. - Lock encapmtx when walking encaptab, modifying it, comparing entries, etc. - Remove spl's. Note that currently there's no facilite to make sure outstanding use of encapsulation methods on a table entry have drained bfore we allow a table entry to be removed. As such, it's currently the caller's responsibility to make sure that draining takes place. Reviewed by: mlaier
