We will currently support only 82599 and x540 deviced. Support for
other devices
will be added later.
- Added a new API version support.
- Added the query implementation in the ixgbevf.
Signed-off-by: Vlad Zolotarov <redacted>

New in v10:
- Expose the _locked function in the vf.h interface according
to the current ixgbevf layering model.
- Return EOPNOTSUPP in cases then operation is not supported.
- Mask the received RETA according to the VF Rx queues
configuration.
- Added IXGBEVF_82599_RETA_SIZE macro.
New in v9:
- Reduce the support to 82599 and x540 devices only.
- Improvements in RETA query code:
- Implement a "compression" of VF's RETA contents: pass only 2
bits
per-entry.
- RETA querying is done in a single mailbox operation thanks to
compression.
New in v8:
- Protect mailbox with a spinlock.
New in v7:
- Add ixgbe_mbox_api_12 case in ixgbevf_set_num_queues().
- Properly expand HW RETA into the ethtool buffer.
New in v6:
- Add a proper return code when an operation is blocked by PF.
New in v3:
- Adjusted to the new interface IXGBE_VF_GET_RETA command.
- Added a proper support for x550 devices.
New in v1 (compared to RFC):
- Use "if-else" statement instead of a "switch-case" for a single
option case
(in ixgbevf_get_reta()).
