Description Jack Bloch 2002-07-12 11:56:17 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)

Description of problem:
I use SIOCSARP to force a permanent IP/MAC combination into the ARP cache. The 
first message I try to send to this device (using UDP/IP) contains 
00:00:00:00:00:00 in the destination MAC address field. Subsequent messages are 
correct. A display of the ARP cache prior to the send shows the entry.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Force IP/MAC combination into ARP cache
2.Send UDP packet to the destination host
3.Look at message on sniffer

Please close this trouble report, the problem was caused by my own device 
driver which I have subsequently corrected.
