New Revision: 196501
URL: http://svn.freebsd.org/changeset/base/196501

Log:
  When registering a protocol to an existing protocol domain via
  pf_proto_register(), iterate over all existing vnets to call protosw_init()
  and thus the appropriate .pr_init() handler in the context of each vnet.
  NB in the future we probably want to separate pr_init() handlers into
  two, i.e. per-vnet and global, functions.
  
  This change has no impact on nooptions VIMAGE builds.
