    iwlwifi: add new -17 firmware for iwlmvm devices

    Revision number: 352738
    Build number: WFFW28817_L14LIN

    This is the last firmware that supports 3160 / 7260 / 7265.
    Newer firmware will support 7265D and up only.

Hello Jesse, or anyone else affected,

Accepted linux-firmware into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/1.157.5 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

This package does fix the issue.
There is no warning anymore, and I could connect to a wifi network correctly.

The verification of the Stable Release Update for linux-firmware has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
