As described in the device tree bindings for 'brcm,bcm4329-fmac'
nodes, the interrupts property is optional. So adding a check
for the presence of this property before attempting to parse
and map the interrupt. If not present or parsing fails return
and fallback to in-band sdio interrupt.

Several of these drivers have there TX randomly blocked for 3~5 seconds while
measuring tx throughput (iperf). The root couse happens in rtl_pci_flush().
The function uses a while-loop to wait for TX queue length to decrease to 0.
The TX queue length counts the number of packets that are queued in the driver.
The driver relys on the TX OK interrupt to return skb and reduce TX queue length.
The interrupt subroutine disables interupts, reads the interrupt registers, and
then clears the registers in the beginning of _rtl_pci_interrupt(). After all
interupts process are finished, the driver invokes enable_interrupt() to enable
interupts. This behavior is normal for an interrupt subroutine.
But enable_interrupt() invokes clear_interrupt() again. This unexpected interrupt
clearing may cleari me fresh TX OK interrupts. These missing interrupts cause TX
queue length to never reduce to 0i, which causes rtl_pci_flush() to be stuck in
unterminated while-loop.
This patch removes clear_interrupt() in enable_interrupt() to avoid this behavior.

The PCI cache line size value was being compared against decimal values
prefixed with 0x.
Fixed the literals to use the correct hex values.
This has not been tested due to lack of hardware. However, the value in
`cline` is PCI cache line size, which is the CPU's cache line size.
It is less likely for cache line sizes to be 22 or 50, and more likely for
them to be 16 or 32. Also, as far as I understand, cache line size is used for
things like aligning DMA requests with CPU cache line, which improve
performance but wouldn't break anything if the value doesn't match. In
this case, we will fall through to the default case which leaves `reg`
unchanged.

mlx4: Enable single ported VFs over IB ports
This series further enhances the support for mlx4 single ported VFs
introduced in 3.15 to work over IB ports too.
Just as quick reminder, the ConnectX3 device family exposes one PCI device
which serves both ports.
This can be non-optimal under virtualization schemes where the admin
would like the VF to expose one interface to the VM, etc.
Since all the VF interaction with the firmware passes through the PF
driver, we can emulate to the VF they have one port, and further create
a set of the VFs which act on port1 of the device and another set which
acts on port2.

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).

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.

Single port VFs always provide port = 1 (even if the actual physical
port used is port 2). As such, we need to convert the port provided
by the VF to the physical port before calling into the firmware.
It turns out that the Linux mlx4 VF RoCE driver maintains a copy of
the GID table and hence this change became critical only for single
ported IB VFs, but it could be needed for other RoCE VF drivers too.

pktgen: cleanups and introducing new samples/pktgen scripts
v3:
- Aborted v2 send due it was not generating diff stat
(this is a bug in stg-mail, if not in the root directory)
v2: address nitpicks from Cong Wang
- Remove useless cat's, but keep them for old pgset()
- Comment on: Due to pgctrl, cannot use exit code $? from grep
- Use arithmetic compare in pktgen_sample03_burst_single_flow.sh
This patchset is focused on making pktgen easier to use and better
documented. It contains a number of documentation updates and minor
changes to pktgen. The major contribution is introduction of common
helper function for sample scripts.
Instead of the old pgset() function, three new shell functions for
configuring the different components of pktgen are introduced:
pg_ctrl(), pg_thread() and pg_set().
The new functions correspond to pktgens different components.
* pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
* pg_thread() control the kernel threads and binding to devices
* pg_set() control setup of individual devices
Helpers also provide consistent parameter parsing across the sample
scripts.
Usage example:
./pktgen_sample01_simple.sh -i eth41 -m 00:12:C0:02:AC:5A -d 192.168.41.2
Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX
-i : ($DEV) output interface/device (required)
-s : ($PKT_SIZE) packet size
-d : ($DEST_IP) destination IP
-m : ($DST_MAC) destination MAC-addr
-t : ($THREADS) threads to start
