Now I reach to use it on -current and, following your advice, on 9.1 too. The patch (for 9.1-release) that I've used his here: http://gugus69.free.fr/freebsd/freebsd.netmap.patch But I didn't adapt the ixgbe drivers (only em and re): - the DEV_NETMAP part in the ixgbe drivers include new -current drivers code and simply copy the full -current ixgbe drivers didn't works - I didn't have this hardware for testing it Tested on virtualbox: [root@router]~# uname -a FreeBSD router.bsdrp.net 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243710M: Wed Jan 9 16:30:29 CET 2013 r...@orange.bsdrp.net:/usr/obj/BSDRP.amd64/usr/local/BSDRP/FreeBSD/src/sys/amd64 amd6 [root@router]~# pkt-gen -i em0 -t 50 -d 1.1.1.2 -D aa:aa:00:00:02:12 -s 1.1.1.1 main [832] ether627.452946 netmap_mmap_single [511] cdev 0xfffffe00022d4a00 foff 0 size 343019520 objp 0xffffff800033ba08 prot 3 _aton(aa:aa:00:00:02:12) gives 0x800f9a292 main [900] map size is 334980 Kb main [922] mmapping 334980 Kbytes 627.461541 netmap_set_ringid [886] ringid em0 set to all 1 HW RINGS Sending on em0: 1 queues, 1 threads and 1 cpus. 1.1.1.1 -> 1.1.1.2 (aa:aa:00:01:01:01 -> aa:aa:00:00:02:12) main [975] Wait 2 secs for phy reset main [977] Ready629.517672 netmap_memory_finalize [724] busy (refcount 2) ... 629.520162 netmap_set_ringid [886] ringid em0 set to all 1 HW RINGS sender_body [479] start main [1085] 50 p630.528557 netmap_ioctl [1073] deprecated, data is 0xffffff800033bbc0 ps 630.531703 netmap_memory_deref [950] refcount = 1 Sent 50 packets,630.533182 netmap_ioctl [1073] deprecated, data is 0xffffff800033bbc0 60 bytes each, in 0.02 seconds.
