Bug Description

[Impact]

The current Xenial bnxt_en driver only supports a limited (old) set of Broadcom NICs. We want to support newer NICs in Xenial without adding risk for existing users.

The plan is to provide a separate driver called bnxt_en_bpo which is a backported driver from Broadcom. This driver will be modified to only support the new NICs that the current kernel driver does not support so that they both can co-exist.

In other words, NICs that used to be supported by Xenial will still be managed by the current (unmodified) bnxt_en driver. Newer NICs will be managed by the new bnxt_en_bpo driver.

[Test Case]

Due to the unavailability of Broadcom HW, the only test that was run was to manually load both the bnxt_en and bnxt_en_bpo module to ensure that they can co-exist.

[Regression Potential]

There should be no regression potential, since the current driver is not modified and the new driver only loads for NICs that are not handled by the current driver.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This is looking great so far. Instance booted nicely, no signs of a
kernel panic. The driver was happily picked up in the initramfs. I'm
going to run it through some stress-ng tests to make sure everything is
fine but we're off to a good start.
