* enum xge_hal_event_e - Enumerates slow-path HAL events.
* @XGE_HAL_EVENT_UNKNOWN: Unknown (and invalid) event.
* @XGE_HAL_EVENT_SERR: Serious hardware error event.
* @XGE_HAL_EVENT_LINK_IS_UP: The link state has changed from 'down' to
* 'up'; upper-layer driver (typically, link layer) is
* supposed to wake the queue, etc.
* @XGE_HAL_EVENT_LINK_IS_DOWN: Link-down event.
* The link state has changed from 'down' to 'up';
* upper-layer driver is supposed to stop traffic, etc.
* @XGE_HAL_EVENT_ECCERR: ECC error event.
* @XGE_HAL_EVENT_PARITYERR: Parity error event.
* @XGE_HAL_EVENT_TARGETABORT: Target abort event. Used when device
* aborts transmit operation with the corresponding transfer code
* (for T_CODE enum see xgehal-fifo.h and xgehal-ring.h)
* @XGE_HAL_EVENT_SLOT_FREEZE: Slot-freeze event. Driver tries to distinguish
* slot-freeze from the rest critical events (e.g. ECC) when it is
* impossible to PIO read "through" the bus, i.e. when getting all-foxes.
*
* xge_hal_event_e enumerates slow-path HAL eventis.
*
* See also: xge_hal_uld_cbs_t{}, xge_uld_link_up_f{},
* xge_uld_link_down_f{}.
