[PATCH v2 0/1] net/mana: add device reset support

[Wei Hu]

From: Wei Hu <weh at microsoft.com>

Add support for handling hardware service reset events in the
MANA driver. 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.

The driver uses ethdev recovery events (ERR_RECOVERING,
RECOVERY_SUCCESS, RECOVERY_FAILED) to notify upper layers of
the reset lifecycle, and a PCI device removal event callback
to distinguish hot-remove from service reset.

Changes since v1:
- Removed net/netvsc patch from this series (will be submitted
  separately)
- Simplified reset exit: mana_reset_exit now calls
  mana_reset_exit_delay directly instead of spawning a separate
  thread, since it already runs on mana_reset_thread
- Added __rte_no_thread_safety_analysis annotations to fix clang
  -Wthread-safety build errors
- Switched from rte_thread_create_control to
  rte_thread_create_internal_control per DPDK preference
- Fixed declaration-after-statement style issues
- Fixed stale comments and removed unnecessary blank lines
- Added comments explaining intentionally ignored return values
