Hello list, I will be grateful if someone could point me to the right direction regarding the question below. My device driver is getting incoming packets fine, but for some reason I am not able to send a single packet. Here is the source code: http://www.freebsd.az/if_ib.c I've added several debug messages to the source and here is the output: / /(bringing interface up and assigning the ip/netmask combination) / ifconfig ib0 192.168.0.6 netmask 255.255.255.0 up /(and here is what I get in /var/log/messages /; /it seems to be a standard arp broadcast) / Feb 7 19:14:32 schizo kernel: ib_init entered Feb 7 19:14:32 schizo kernel: ib_start entered Feb 7 19:14:32 schizo kernel: ib_encap entered Feb 7 19:14:32 schizo kernel: DHOST ff ff ff ff ff ff Feb 7 19:14:32 schizo kernel: SHOST 0 c0 ee 22 3 14 Feb 7 19:14:32 schizo kernel: txeof entered Feb 7 19:14:32 schizo kernel: txeof exiting /(now I try pinging, but no joy . I've added extra debug messages inside ping.c) /schizo# ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1): 56 data bytes packets sent: -1 ping: sendto: Invalid argument packets sent: -1 ping: sendto: Invalid argument packets sent: -1 ping: sendto: Invalid argument ^C --- 192.168.0.1 ping statistics --- 3 packets transmitted, 0 packets received, 100% packet loss / I have also tied to add debug messages to sys/net/if.c and sys/net/netisr.c and it seems that the kernel doesn't even try to run my ib_start() function. Any comments are appreciated.
