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:
Always.

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
0.0.0.0         0.0.0.0         0.0.0.0         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.

I can confirm this bug, with this hardware.

The "ifconfig usb0 -arp" workaround works.

Huh, quite odd.  Probably something we should do for all 3G devices that
provide eth ports, since they are all acutally point-to-point
underneath.  I have just bought a K3805z off ebay that I can use to test
this out when it arrives.

@Dan Williams : Hello! Just to point out you will also find bug #745454
if using Gnome-Shell ;)

Also, I don't know if all devices are affected. Looking at
https://github.com/andrewbird/wader/blob/master/resources/udev/99-wader-
quirks.rules you can see a relatively small list of quirks.

(that URL is the temporary Git repo of Vodafone's
https://forge.betavine.net/projects/bcm (which curiously is hidden from
public project list), as the result of the migration off SVN
https://forge.betavine.net/forum/forum.php?forum_id=245 )

This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

At least on Fedora 18, the device is now recognized as "wwan0" and no
longer requires ifconfig INTERFACE_NAME -arp .

Closing bug.
