43 * @XGE_HAL_EVENT_LINK_IS_UP: The link state has changed from 'down' to
44 * 'up'; upper-layer driver (typically, link layer) is
45 * supposed to wake the queue, etc.

49 * @XGE_HAL_EVENT_ECCERR: ECC error event.
50 * @XGE_HAL_EVENT_PARITYERR: Parity error event.
51 * @XGE_HAL_EVENT_TARGETABORT: Target abort event. Used when device
52 * aborts transmit operation with the corresponding transfer code
53 * (for T_CODE enum see xgehal-fifo.h and xgehal-ring.h)
54 * @XGE_HAL_EVENT_SLOT_FREEZE: Slot-freeze event. Driver tries to distinguish
55 * slot-freeze from the rest critical events (e.g. ECC) when it is
56 * impossible to PIO read "through" the bus, i.e. when getting all-foxes.
