better late than never...
The following two additions to sys/net/netmap_user.h
(or for the linux version, include/net/netmap_user.h )
should enable compilation of click.

	#define NETMAP_RING_FIRST_RESERVED(r)                   \
		( (r)->cur < (r)->reserved ?                    \
		  (r)->cur + (r)->num_slots - (r)->reserved :   \
		  (r)->cur - (r)->reserved )

	/* one field in struct nmreq was renamed */
	#define nm_numrings	nr_rx_rings

i have already committed the former to FreeBSD/head, while
the latter is not there because i would prefer to fix the
one or two places in the Click sources.
