Re: kern/48964 (In urndis(4), initialization of ifnet structure is not enough, cause panic.)

[from diff]:

        if (ifp->if_flags & IFF_RUNNING)
-          return;
+          return EBUSY;

I don't know whether if_init() will be called or not when IFF_RUNNING flag is 
it will depend on the design of network (or ethernet) driver.

It seems that many nic drivers are stopping I/O, resetting and re-initializing,
or some drivers skip lator and return with 0 in this case.
at least I could not find another drivers which returns with any ERROR.
