Hi Alexander,
I'd presume umb(4) does not depends on netmap. A quick search of DEV_NETMAP
```
#ifdef DEV_NETMAP
static void umb_input(if_t , struct mbuf *);
#endif
...
#ifdef DEV_NETMAP
if_setinputfn(ifp, umb_input);
#endif
```
I think the #ifdef can be removed. I currently do not have that hardware so I'd
appreciate if someone can test it.
Best regards,
Zhenlei
