I have no idea why I haven't thought about interface capabilities,
but that's certainly what I was looking for, thanks!

Since this was very easy to implement, and it also didn't require
change to basic polling code (the IFF_POLLING has the old meaning
and semantics), I went ahead and committed my updated changes to
HEAD.

The new IFCAP_POLLING will be set by default in enabled capabilities
list, except probably in the rl(4) driver.  ;)

Is it really "all the time"?  The use of IFF_CANTCHANGE is currently
limited to only two files in sys/net/, if I'm not terribly mistaken.
Anyway, let's continue discussion of this item in a separate thread.
