IB/IPoIB: Don't update neigh validity for unresolved entries

2016-06-07T14:49:48+00:00

ipoib_neigh_get unconditionally updates the "alive" variable member on
any packet send.  This prevents the neighbor garbage collection from
cleaning out a dead neighbor entry if we are still queueing packets
for it.  If the queue for this neighbor is full, then don't update the
alive timestamp.  That way the neighbor can time out even if packets
are still being queued as long as none of them are being sent.

IB/mlx5: Fix alternate path code

2016-06-07T14:03:50+00:00

Userspace flag IBV_QP_ALT_PATH is supposed to set the alternate path
including fields alt_pkey_index and alt_timeout.
Added IB_QP_PKEY_INDEX and IB_QP_TIMEOUT to the attribute mask when
calling mlx5_set_path for the alternate path to force setting the
alt_pkey_index and alt_timeout values.

IB/mlx5: Fix pkey_index length in the QP path record

2016-06-07T14:03:50+00:00

Pkey index fields in the QP context path record are extended to 16
bits, as required by IB spec (version 1.3).
This change affects all QP commands which include path records.

To enable this change, moved the free adaptive routing flag bit
(free_ar) to the most significant byte of the QP path record.

IB/mlx5: Return PORT_ERR in Active to Initializing tranisition

2016-06-07T14:03:49+00:00

FW port-change events are fired on Active <-> non Active port state
transitions only.
When the port state changes from Active to Initializing (Active ->
Down -> Initializing), a single event is fired.
The HCA transitions from Down to Initializing unless prevented from
doing so, hence the driver should also propagate events when the port
state is Initializing to consumers so they'll be aware that the port
is no longer Active and act accordingly.
