Subject: Intel 82567LM e1000e DHCP problem/question

Hi,

Quick question.

Is there any functionality inside the driver for DHCP request.
I see in the source that there is some kind of DHCP filter f the tx stream.
Can the drive issue DHCP request inside it self when the Cable is unplugged/plugged.

I'm tracing a DHCP fault. 
When the net is brought down, ifdown eth0, the dhclient is killed.
Then when I unplugged/plugged the cable I get a DHCP request even that 
dhclient is down.

Also the Wireshark format of the DHCP request are different.
Correct request includes from dhclient has:
> Option: (t=12,l=5) Host Name = "pc005"
Incorrect requests when dhclient is killed dose not have above.

/Thanks
