Experimental support for opportunitic use of jumbograms where only some hosts
on the local network support them.
This adds a new socket option, SO_JUMBO, and a new route flag,
RTF_JUMBO. If _both_ the socket option is set and the route for the host
has RTF_JUMBO set, ip_output will fragment the packet to the largest
possible size for the link, ignoring the card's MTU.
The semantics of this feature will be evolving rapidly; talk to us
if you intend to use it.
