Subject: [PATCH net-next v4 0/2] Handle alternate miss-completions

Some versions of the virtual NIC present miss-completions in
an alternative way. Let the diver handle these alternate completions
and announce this capability to the device.

The capability is announced uing a new AdminQ command that sends
driver information to the device. The device can refuse a driver
if it is lacking support for a capability, or it can adopt it's
behavior to work around it.

Changed in v4:
- Clarified new AdminQ command in cover letter
- Changed EOPNOTSUPP to ENOTSUPP to match device's response
Changed in v3:
- Rewording cover letter
- Added 'Reviewed-by: Jesse Brandeburg <jesse.brandeburg@...el.com>'
Changes in v2:
- Changed the subject to include 'gve:'
