URL: http://svn.freebsd.org/changeset/base/206428 Log: This commit enables partial operation of dummynet with kernels compiled with "options VIMAGE". As it is now, there is still a single instance of the pipes, and it is only usable from vnet0 (the main instance). Trying to use a pipe from a different vimage does not crash the system as it did before, but the traffic coming out from the pipe goes to the wrong place, and i still need to figure out where. Support for per-vimage pipes is almost there (just a matter of uncommenting the VNET_* definitions for dn_cfg, plus putting into the structure the remaining static variables), however i need first to figure out how init/uninit work, and also to understand where packets are ending up on exit from a pipe. In summary: vimage support for dummynet is not complete yet, but we are getting there.
