There is another place in our network code you can get ENOBUFS from,
unrelated to the number of kernel mbufs; see PR 7285

See also src/sys/net/if.{c,h} and IF_QFULL() macro.

We really, really need to have a separate errno for "network interface queue 
full", ideally coordinated with our "sister" BSD's and ... Linux.
