Reason is: in the function assigned to net_device_ops->ndo_stop, the steps
for bringing down the interface are done in the wrong order. The step that
notifies the NIC firmware to stop forwarding packets to host is done too
late. Fix it by moving that step to the beginning.

Defer ringing the Tx doorbell if skb->xmit_more is set unless the Tx queue
is full or stopped. To keep latency low, use a deferral limit of 8
packets. We chose 8 because Octeon can fetch at most 8 packets in a single
PCI read, and our tests show that 8 results in low latency.

Deprecate the 1-bit flag (bit 2 in the SLI_SCRATCH_1 Octeon register) that
indicates that the liquidio watchdog kernel thread is running for this NIC.
Reason is: it is incompatible with the firmware's use for SLI_SCRATCH_1.
In lieu of checking that now-deprecated flag, check the value of
oct_dev->adapter_refcount to determine whether or not to create the
watchdog kernel thread.

There were quite a few overlapping sets of changes here.
Daniel's bug fix for off-by-ones in the new BPF branch instructions,
along with the added allowances for "data_end > ptr + x" forms
collided with the metadata additions.
Along with those three changes came veritifer test cases, which in
their final form I tried to group together properly. If I had just
trimmed GIT's conflict tags as-is, this would have split up the
meta tests unnecessarily.
In the socketmap code, a set of preemption disabling changes
overlapped with the rename of bpf_compute_data_end() to
bpf_compute_data_pointers().
Changes were made to the mv88e6060.c driver set addr method
which got removed in net-next.
The hyperv transport socket layer had a locking change in 'net'
which overlapped with a change of socket state macro usage
in 'net-next'.

While experimenting with changes to the timekeeping code, I
ran into a build error in the liquidio driver:
drivers/net/ethernet/cavium/liquidio/lio_main.c: In function 'liquidio_ptp_settime':
drivers/net/ethernet/cavium/liquidio/lio_main.c:1850:22: error: passing argument 1 of 'timespec_to_ns' from incompatible pointer type [-Werror=incompatible-pointer-types]
The driver had a type mismatch since it was first merged, but
this never caused problems because it is only built on 64-bit
architectures that define timespec and timespec64 to the same
type.
If we ever want to compile-test the driver on 32-bit or change
the way that 64-bit timespec64 is defined, we need to fix it,
so let's just do it now.

Fix crash in linux PF driver when BARs have been cleared/de-programmed;
fail early init (prior to mapping BARs) if the BAR0 or
BAR1 registers are zero.
This situation can arise when the PF is added to a VM (PCI pass-through),
then a PF FLR is issued (in the VM). After this occurs, the BAR registers
will be zero. If we attempt to load the PF driver in the host
(after VM has been shutdown), the host can reset.

struct call_single_data is used in IPIs to transfer information between
CPUs. Its size is bigger than sizeof(unsigned long) and less than
cache line size. Currently it is not allocated with any explicit alignment
requirements. This makes it possible for allocated call_single_data to
cross two cache lines, which results in double the number of the cache lines
that need to be transferred among CPUs.
This can be fixed by requiring call_single_data to be aligned with the
size of call_single_data. Currently the size of call_single_data is the
power of 2. If we add new fields to call_single_data, we may need to
add padding to make sure the size of new definition is the power of 2
as well.
Fortunately, this is enforced by GCC, which will report bad sizes.
To set alignment requirements of call_single_data to the size of
call_single_data, a struct definition and a typedef is used.
To test the effect of the patch, I used the vm-scalability multiple
thread swap test case (swap-w-seq-mt). The test will create multiple
threads and each thread will eat memory until all RAM and part of swap
is used, so that huge number of IPIs are triggered when unmapping
memory. In the test, the throughput of memory writing improves ~5%
compared with misaligned call_single_data, because of faster IPIs.

In the NIC firmware, the 1-bit flag indicating "firmware is loaded" moved
from SLI_SCRATCH_1 to SLI_SCRATCH_2 (these are Octeon general-purpose
scratch registers). Make the PF driver conform to this change.
Remove code that sets the "firmware is loaded" flag because it's now the
firmware's job to do that.
In the code that detects whether or not the firmware is loaded, don't just
rely on checking the "firmware is loaded" flag because that may cause a
rare false negative. Add code that deduces whether or not the firmware is
loaded; that will never give a false negative.
Also bump up driver version to match newer NIC firmware.
