wmaster missing in udev

Bug Description

Binary package hint: udev

The new iwlist driver for the intel wireless cards 3945 etc installs a second `interface' called wmaster.
When upgrading from iwp3945 to ivl3945 udev gets confused and tries to rename the real interface from
wlan0 to eth1 since there is a corresponding entry in 70-persistent-net.rules. It gets stuck and ends up with an
interface named wla0_rename.

Fix: adding `wmaster*' to the pattern for network cards in 75-persistent-net-generator.rules worked for me.
It then created a rule in 70-persistent-net.rules:

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="xxxxxxxxxxxxx", NAME="wmaster0"

and permitted to leave the one for the real interface

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="xxxxxxxxxxxxxxxxxx", ATTRS{type}=="1", NAME="eth1"

unchanged. In particular this leaves the name of the interface to what it had been (eth1 for me), which is preferable for
not having to change other scripts.
