Comment 10 for bug 1715368

Hi Joseph,
Did we zero down on the kernel that we see this issue with.
Can we pull in the latest bnxt driver for 16.04.03 updates ?

Thanks,
Anand

missing in 16.04.03 'kernel-fixed-upstream'

The purpose of going through a "Reverse" bisect is to identify the commit
that fixes this bug and adds the proper CuW B1 device IDs. To do that, we
would want to figure out the last kernel that did not have the ids and the
first kernel that did.

However, it sounds like all the upstream kernels you tested so far do not
exhibit this bug (4.4 -> 4.13), but the 16.04.3 kernel does have the bug?

Also, the 16.04.3 kernel should be 4.10 based, but you see version 4.4.0-87?
Is that correct?
