42 * enum xge_hal_event_e - Enumerates slow-path HAL events.
43 * @XGE_HAL_EVENT_UNKNOWN: Unknown (and invalid) event.
44 * @XGE_HAL_EVENT_SERR: Serious hardware error event.
45 * @XGE_HAL_EVENT_LINK_IS_UP: The link state has changed from 'down' to
46 * 'up'; upper-layer driver (typically, link layer) is
47 * supposed to wake the queue, etc.
48 * @XGE_HAL_EVENT_LINK_IS_DOWN: Link-down event.
49 *                    The link state has changed from 'down' to 'up';
50 *                    upper-layer driver is supposed to stop traffic, etc.
51 * @XGE_HAL_EVENT_ECCERR: ECC error event.
52 * @XGE_HAL_EVENT_PARITYERR: Parity error event.
53 * @XGE_HAL_EVENT_TARGETABORT: Target abort event. Used when device
54 * aborts transmit operation with the corresponding transfer code
55 * (for T_CODE enum see xgehal-fifo.h and xgehal-ring.h)
56 * @XGE_HAL_EVENT_SLOT_FREEZE: Slot-freeze event. Driver tries to distinguish
57 * slot-freeze from the rest critical events (e.g. ECC) when it is
58 * impossible to PIO read "through" the bus, i.e. when getting all-foxes.
59 *
60 * xge_hal_event_e enumerates slow-path HAL eventis.
61 *
62 * See also: xge_hal_uld_cbs_t{}, xge_uld_link_up_f{},
