not your mistake, on stable/9 i have not merged yet the device driver changes. Your best option is to copy sys/dev/netmap from HEAD, and add the device-specific chunks also from HEAD into the various drivers (dev/e1000, dev/ixgbe, dev/re) The changes are clearly identified by #ifdef DEV_NETMAP/#endif blocks. cheers luigi > [root@HOST1]~# uname -r > 9.1-RELEASE > [root@HOST1]~# kldload netmap > 018.237252 netmap_new_obj_allocator [425] objsize 1024 clustsize 4096 objects > 4 > 018.248826 netmap_new_obj_allocator [503] Pre-allocated 128 clusters > (4/512KB) for 'netmap_if' > 018.252891 netmap_new_obj_allocator [425] objsize 36864 clustsize > 36864 objects 1 > 018.257305 netmap_new_obj_allocator [503] Pre-allocated 200 clusters > (36/7200KB) for 'netmap_ring' > 018.259826 netmap_new_obj_allocator [425] objsize 2048 clustsize 4096 objects > 2 > 018.332819 netmap_new_obj_allocator [503] Pre-allocated 50000 clusters > (4/200000KB) for 'netmap_buf' > 018.351183 netmap_memory_init [553] Have 512 KB for interfaces, 7200 > KB for rings and 195 MB for buffers > netmap: loaded module with 202 Mbytes > > [root@HOST1]~# ifconfig em0 > em0: flags=8843<UP,BROADCAST, > RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> > ether aa:aa:00:01:01:01 > inet 1.1.1.1 netmask 0xffffff00 broadcast 1.1.1.255 > inet6 fe80::a8aa:ff:fe01:101%em0 prefixlen 64 scopeid 0x1 > nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> > media: Ethernet autoselect (1000baseT <full-duplex>) > status: active > > [root@HOST1]~# ping -c 1 1.1.1.2 > PING 1.1.1.2 (1.1.1.2): 56 data bytes > 64 bytes from 1.1.1.2: icmp_seq=0 ttl=64 time=0.466 ms > > --- 1.1.1.2 ping statistics --- > 1 packets transmitted, 1 packets received, 0.0% packet loss > round-trip min/avg/max/stddev = 0.466/0.466/0.466/0.000 ms > [root@HOST1]~# arp 1.1.1.2 > ?
