This series adds support for handling hardware service reset events
in the MANA and netvsc drivers.
When the MANA kernel driver receives a hardware service event, it
initiates a device reset and notifies userspace via
IBV_EVENT_DEVICE_FATAL. The MANA PMD handles this by performing an
automatic teardown and recovery sequence, using ethdev recovery
events (ERR_RECOVERING, RECOVERY_SUCCESS, RECOVERY_FAILED) to
notify upper layers.
Patch 1 implements the reset logic in the MANA driver, including
RCU-based data path quiescence, multi-process doorbell remap via
IPC, and a control thread for the recovery sequence.
Patch 2 adds recovery event handlers in the netvsc driver so it
can switch the data path to synthetic during reset and back to VF
after successful recovery.
