[PATCH net-next] ixgbevf: Remove unused ixgbevf_hv_mbx_ops

[PATCH net-next] ixgbevf: Remove unused ixgbevf_hv_mbx_ops

[linux]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

The const struct ixgbevf_hv_mbx_ops was added in 2016 as part of
commit c6d45171d706 ("ixgbevf: Support Windows hosts (Hyper-V)")

but has remained unused.

The functions it references are still referenced elsewhere.

Remove it.

Hi Jakub,

Hmm, do you have a link to that report, or to which tree I should try
applying it to.

net-next, the tree in the subject prefix:

Oh I see, it's the e610 patch that crept in and just changed the context
and moved the lines down a bit; not built it yet, but I'll cut a new version.

See below.
