Description of problem:
After kernel update to 2.6.22.1-32.fc6 I can't get the ethernet interface on my
Dell Inspiron 5150 to work. The wireless interface works without problems when I
enable it.

The problem is first noticed when using DHCP, when tracing on the DHCP server
(using tcpdump) and the laptop (using wireshark) I can see the laptop sending a
DHCP REQUEST message, and the server receiving it and replying with an OFFER,
the OFFER is never received by the laptop, wireshark doesn't see the reply at all.

lspci gives the following data on the network interface:
02:01.0 Ethernet controller: Broadcom Corporation BCM4401 100Base-T (rev 01)
I think the module used for this controller is called b44

Flushing iptables with iptables -F doesn't help.

Version-Release number of selected component (if applicable):
2.6.22.1-32.fc6

How reproducible:
Activating the DHCP configured eth0 interface will fail with a tiemout after 5 tries

Steps to Reproduce:
1. ifdown eth0
2. ifup eth0
  
Actual results:
Timeout on the DHCP requests

Expected results:
Normal DHCP protocol being followed as happened before
