Hi,

Without patch the iwlwifi/iwldvm driver does not accept the 7260 AC card in an
Asus TP300LA laptop of a friend. Another report can be found on
<https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/254548>.

By the way, initially I tried to write '8086 08b1 8086 4c70' (and also just the
first two words) to /sys/bus/pci/drivers/iwlwifi/new_id, and '0000:02:00.0' to
/sys/bus/pci/drivers/iwlwifi/bind, but I got EINVAL and ENODEV respectively.
Why did this not work?

Kind regards,
Peter
