Description of problem:
When connecting to my mobile phone using bluetooth & Internet Sharing on my
phone, bnep0 comes up but does not get an IP address via DHCP. Running dhclient
manually makes the connection work - however this should be handled via
NetworkManager.

Version-Release number of selected component (if applicable):
NetworkManager-glib-0.8.1-6.git20100831.fc14.i686
NetworkManager-0.8.1-6.git20100831.fc14.i686
NetworkManager-gnome-0.8.1-6.git20100831.fc14.i686

How reproducible:
Every time.

Steps to Reproduce:
1. Use a HTC Windows Mobile Phone & set up Internet Sharing.
2. Pair PC to phone via bluetooth
3. Connect to PC form phone with Internet Sharing app.
4. run: ifconfig bnep0 - note no IP address assigned.

Actual results:
no IP address on bnep0 interface.

Expected results:
As no interface is configured for bnep0, NetworkManager should see that bnep0
has been created, then run dhclient to get an address via DHCP.

Interestingly enough - I tried this with F13 + updates-testing.

In /var/log/messages I saw this:

Sep 23 18:58:07 eeepc ntpd[1326]: Listen normally on 7 bnep0
fe80::1e4b:d6ff:fe0c:356e UDP 123

This means if NetworkManager can be told about the device driver settings to
allow the PAN connection to work, it may be trivial to correct this.

Reconnecting my PAN connection, I looked in the above directory and the file
uevent shows:
DEVTYPE=bluetooth
INTERFACE=bnep0
IFINDEX=7
