On reboot SM can program port pkey table before ipoib registered its
event handler, which could result in missing pkey event and leave root
interface with initial pkey value from index 0.

Since OPA port starts with invalid pkey in index 0, root interface will
fail to initialize and stay down with no-carrier flag.

For IB ipoib interface may end up with pkey different from value
opensm put in pkey table idx 0, resulting in connectivity issues
(different mcast groups, for example).

Close the window by calling event handler after registration
to make sure ipoib pkey is in sync with port pkey table.

The routine which shows the fault stats checks the counters
to determine whether to show any stats based on the number of
transmitted pkts/bytes for a particular opcode.

Unfortunately, it only checked the receive counters. As a result,
if any packet faults have happened for packets egressing the HFI,
those stats would not be shown.

In order to fix this, the routine is amended to also check the
TX counters. With this change the pkt/byte counts are the sum of
both TX and RX counts for the opcode.

HFI's counters SendWaitCnt and SendWaitVlCnt are in units
of TXE cycle time (at 805MHz). OPA counters PortXmitWait and
PortVLXmtWait are in units of flit times.
Convert the counter values to flit units using following
conversion formula:

PortXmitWait =
	SendWaitCnt * 2 * (4 /link_width) * (25 Gbps /link_speed)
PortVLXmitWait =
	SendWaitVLCnt * 2 * (4 /link_width) * (25 Gbps /link_speed)

At link up or downgrade events, the link width can change. To ensure
accurate counter calculations, sample the counters after the events,
during counter requests, and then aggregate the OPA counters.

The arguments for trace_hfi1_rcvhdr() get computed every
time in the hot path regardless of the whether the trace

The handling of fault inject isolates the verbs device for

Fix the first by computing trace_hfi1_rcvhdr() arguments within
the trace itself, so that when the trace is off, the argument

packet was already built on a previous iteration of the
send engine. This variable assumed the protection of the
QP's RVT_S_BUSY flag, which was required since the the
QP's s_lock was dropped just prior to the packet being
queued on the one of the egress mechanisms.

Support for multiple send engine instantiations require
that the field not be used due to concurency issues.
The ps.txreq signals the "already built" without the
potential concurency issues.

The pci_request_irq() interfaces always adds the IRQF_SHARED bit to
all IRQ requests.

When the kernel is built with CONFIG_DEBUG_SHIRQ config flag, if the
IRQF_SHARED bit is set, a call to the IRQ handler is made from the
__free_irq() function. This is testing a race condition between the
IRQ cleanup and an IRQ racing the cleanup.  The HFI driver should be
able to handle this race, but does not.

This race can cause traces that start with this footprint:

  other resources, eliminating the race.

  Re-order error path for init so that the race does not occur.
