      net/mlx4_core: Modify port values when generting EQEs for VFs · 74d4943f
      由 Or Gerlitz 提交于 
      As part of enabling single ported VFs over IB ports we need to handle
some of the flows for generting EQ events for VFs which don't come
into play under Eth ports.

This mainly includes port management events derived from changes of the
phyiscal port (lid change, client re-register, down/up, etc), VF pkey table
changes and VF guid changes initiated by the IB driver.

(1) make sure that events are generated only for VFs sitting on
    the relevant physical port (under the ALL_SLAVES flow).

(2) before generating the event, convert from physical (one or two)
    to VF port (always equals one).

      IB/mlx4: Convert slave port before building address-handle · 430910b1
      由 Or Gerlitz 提交于 
      When multiplexling a MAD sent from VF, we should convert the port used
by the guest to send the packet to the actual physical port which will be
used to transmit the packet, before building the relevant address-handle (AH).

This is needed under VPI for single ported VFs, since the code that builds
the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we
use the port number provided by the guest, it might have different protocol
vs. the one this packat has to go from, and hence the result could be wrong.

So far, the conversion was done after the AH was built and it worked for
single ported Eth VFs which were not enabled under VPI. When adding support
for single ported IB VFs and VPI, we hit that.

      IB/mlx4: Reset flow support for IB kernel ULPs · 35f05dab
      由 Yishai Hadas 提交于 
      The driver exposes interfaces that directly relate to HW state. Upon fatal
error, consumers of these interfaces (ULPs) that rely on completion of
all their posted work-request could hang, thereby introducing dependencies
in shutdown order.  To prevent this from happening, we manage the
relevant resources (CQs, QPs) that are used by the device. Upon a fatal error,
we now generate simulated completions for outstanding WQEs that were not
completed at the time the HW was reset.

It includes invoking the completion event handler for all involved CQs so that
the ULPs will poll those CQs. When polled we return simulated CQEs with
IB_WC_WR_FLUSH_ERR return code enabling ULPs to clean up their resources and
not wait forever for completions upon receiving remove_one.

The above change requires an extra check in the data path to make sure that when
device is in error state, the simulated CQEs will be returned and no further
WQEs will be posted.

      IB/mlx4: Always use the correct port for mirrored multicast attachments · 824c25c1
      由 Moni Shoua 提交于 
      When attaching a QP to a multicast address in bonded mode, there was an
assumption that the port of the QP must be #1. This assumption isn't the
case under the flow which enables maximal usage of the physical ports.

Fix it by always checking the port of the original flow and create the
mirrored flow on the other port.
