Comment 40 for bug 764003

Description of problem:
Vodafone k3805-z requires "ifconfig usb0 -arp" prior to connecting to achieve connectivity

Version-Release number of selected component (if applicable):
0.4.998 - 1.git20110706.fc15

How reproducible:

Steps to Reproduce:
1. plug usb modem and workaround whatever needed to connect (#697122)
2. try to ping/access some site

Actual results:
Nothing happens (Wireshark shows ARP requests being sent to every IP one tries to connect with)

Expected results:
Ping should be successful.

Additional info:
$ route -n [with or without NOARP]
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface U 0 0 0 usb0

Also, the driver on Windows 7 has an option which says "Enable promiscuous mode" (?on a 3G pen?) which, after enabled, results on the same behavior as if one does "ifconfig usb0 arp" on Linux.
