Parity errors might happen in the device's memories due to momentary bit flips which are caused by radiation. Errors that are not correctable initiate a process kill event, which blocks the device access towards the host and the network, and a recovery process is started in the management FW and in the driver.
This series adds the support of this process in the qed core module and in the qede driver (patches 2 & 3). Patch 1 in the series revises the load sequence, to avoid PCI errors that might be observed during a recovery process.
