Sending packets   
Hello.

I have some difficulties on my driver to send packets.
For packet reception, it's OK, but I have any TX activities...

For example, I'm pinging from the target my devel host, in order to generate a TX trafic, and I get the following 
message : 

# ping 192.168.38.31
PING 192.168.38.31 (192.168.38.31): 56 data bytes
ping: sendto: Network is down
ping: sendto: Network is down
ping: sendto: Network is down
ping: sendto: Network is down
ping: sendto: Network is down
ping: sendto: Network is down

The if_start function is never called, and I do not get any TX interrupt.

Can you please advise me on the point I shall verify, and why if_startis never called.

Thank you very much.
Guillaume.

'ifconfig <iface>' should show (IFF_RUNNING|IFF_UP).  The
IFF_RUNNING flag is under the driver's control.  Please see
sys/dev_qnx/sample/sam.c
