Subject: [PATCH 0/9] crypto: qat - improve recovery flows

This set improves the error recovery flows in the QAT drivers and
adds a mechanism to test it through an heartbeat simulator.

When a QAT device reports either a fatal error, or an AER fatal error,
or fails an heartbeat check, the PF driver sends an error notification to
the VFs through PFVF comms and if `auto_reset` is enabled then
the device goes through reset flows for error recovery.
If SRIOV is enabled when an error is encountered, this is re-enabled after
the reset cycle is done.

  crypto: qat - add heartbeat error simulator
  crypto: qat - add auto reset on error

Furong Zhou (3):
  crypto: qat - add fatal error notify method
  crypto: qat - disable arbitration before reset
  crypto: qat - limit heartbeat notifications

Mun Chun Yep (4):
  crypto: qat - update PFVF protocol for recovery
  crypto: qat - re-enable sriov after pf reset
  crypto: qat - add fatal error notification
  crypto: qat - improve aer error reset handling
