History
Garrett Wollman 9c9137ea6c Three speed-ups in the output path (two small, one substantial): 
1) Require all callers to pass a valid route pointer to ip_output()
   so that we don't have to check and allocate one off the stack
   as was done before.  This eliminates one test and some stack
    bloat from the common (UDP and TCP) case.

2) Perform the IP header checksum in-line if it's of the usual length.
    This results in about a 5% speed-up in my packet-generation test.

3) Use ip_vhl field rather than ip_v and ip_hl bitfields.
