Intel 3165 NGW combo needs new firmware

[Adam Lee]

Intel 3165 NGW combo needs new firmware iwlwifi-7265D-13.ucode, which is not in linux-firmware repo yet. We need to backport it after it merged.

[Seth Forshee (sforshee)]

Retasked to linux-firmware rather than linux. I declined the vivid task since the max ucode API supported in 3.19 is -12. This also won't be needed in trusty until after 15.10 releases.

@Seth, 3615 is the wireless module or braswell, shouldn't we support it in 3.19 branch?

should I open a linux task to bump the firmware version, or we plan not to support it in 3.19? thanks.

[Seth Forshee (sforshee)]

We can consider bumping the firmware version reported by the kernel, but we need to be sure that it's going to work correctly. In this case it's upstream commit 560ba3e6f4ca31ff884fb238a16032e0e9c5814a which bumps the API number but there are a number of commits preceding this related to how the driver interacts with the firmware. I have no idea whether or not these are required for interacting correctly with the -13 ucode, so I would want to get confirmation from Intel that bumping the ucode API in 3.19 isn't going to cause problems.
