Added helper function to read IB standard error counters
via the PPCNT register.
The PPCNT register read command provides the 32-bit error counters
of both IB/RoCE link layer and transport layer.

Since the wait list is not protected against concurrent access
it must be processed from the context of the completion handler.
Replace the wait list processing code in the IB CM RTU callback
handler by code that triggers a completion handler. This patch
fixes the following rare crash:

If an initiator observes LUN deletion during shutdown of the
target stack then that will trigger an I/O error even when using
multipathd. Users need a way to avoid that shutting down the
target stack causes I/O errors, e.g. by providing a way to force
initiator logout. Hence close all sessions if a target port is
disabled.

The Last WQE Reached event is only generated after one or more work

session shutdown can start before any work requests have been queued,
use a zero-length RDMA write to wait until a QP has been drained.

srpt_abort_cmd() must not be called in state SRPT_STATE_DATA_IN. Issue
a warning if this occurs.
srpt_abort_cmd() must not invoke target_put_sess_cmd() for commands
in state SRPT_STATE_DONE because the srpt_abort_cmd() callers already
do this when necessary. Hence remove this call.
If an RDMA read fails the corresponding SCSI command must fail. Hence
add a transport_generic_request_failure() call.
Remove an incorrect srpt_abort_cmd() call from srpt_rdma_write_done().
Avoid that srpt_send_done() calls srpt_abort_cmd() for finished SCSI
commands.

Add support for receiving multicast/unicast traffic with
the don't trap rule.
Sniffing these packets requires a flow steering rule of type NORMAL
at priority 0 with flag IB_FLOW_ATTR_FLAGS_DONT_TRAP set.
Choosing between multicast or unicast is done via ethernet L2 dest_mac
mask and value:
- If mask is all zeros - unicast and multicast are set.
- If mask non zero - only mask with multicast bit 1 and rest 0 is
supported, the mac value will choose if it is
multicast or unicast rule.
If the mask multicast bit is on and some other bits are on too, it means
a request for specific multicast or unicast, this is not supported,
either receive all multicast or all unicast.
Only when limitations are met registered QP will receive requested type
but other QPs can receive same traffic if registered for it.
Otherwise, if limitations are not met, an error will be returned.
Limitations:
- Rule must be with priority 0.
- A0 mode is not supported.
- Sniffer QP cannot appear in any other flow steering rule.

Don't trap flag (i.e. IB_FLOW_ATTR_FLAGS_DONT_TRAP) indicates that QP
will receive traffic, but will not steal it.
When a packet matches a flow steering rule that was created with
the don't trap flag, the QPs assigned to this rule will get this
packet, but matching will continue to other equal/lower priority
rules. This will let other QPs assigned to those rules to get the
packet too.
If both don't trap rule and other rules have the same priority
and match the same packet, the behavior is undefined.
The don't trap flag can't be set with default rule types
(i.e. IB_FLOW_ATTR_ALL_DEFAULT, IB_FLOW_ATTR_MC_DEFAULT) as default rules
don't have rules after them and don't trap has no meaning here.

This series provides support for iWARP applications to specify a TOS
value and have that map to a VLAN Priority for iw_cxgb4 iWARP connections.
In iw_cxgb4, when allocating an L2T entry, pass the skb_priority based
on the tos value in the cm_id. Also pass the correct tos value during
connection setup so the passive side gets the client's desired tos.
When sending the FLOWC work request to FW, if the egress device is
in a vlan, then use the vlan priority bits as the scheduling class.
This allows associating RDMA connections with scheduling classes to
provide traffic shaping per flow.
