Apply some fixes post rS336659, which allowed multiple provders to be
initialized in a single command.
- Fix issue where second and subsequent providers would fail init.
This was due to the metadata struct being zeroed after the first
provider init was completed, despite containing common data required
for subsequent providers.
- Fix issue where -B "none" would still result in the metadata being
backed-up if multiple providers had been specified. This was due to
the backupfile of "none" being incorrectly made unique for each
provider by appending "-<prov>".

For RoCE, when CM requests are received for RC and UD connections,
netdevice of the incoming request is unavailable. Because of that CM
requests are always forwarded to init_net namespace.
Now that we have the GID index available, introduce SGID index in
incoming CM requests and refer to the netdevice of it.
While at it fix some incorrect uses of init_net and make sure
the rdma_create_id() function stores the VNET it is passed.

While executing vm_pqbatch_process_page(m), m->queue may change to
PQ_NONE if the page daemon is concurrently freeing the page. In this
case m's queue state flags must be clear, so vm_pqbatch_process_page()
will be a no-op, but the race could cause spurious assertion failures.
Correct the assertion which assumed that m->queue's value does not
change while the page queue lock is held.

found that performance was no worse and usually better when running
with TRIM consolidation. Performance improvement was most noticable
when multiple large files are released in a short period of time.
Thus, TRIM consolidation is being enabled by default. Should
operational problems be found, it can be disabled using the command
`sysctl vfs.ffs.dotrimcons=0'. This variable can also be set as a
tunable if early disabling is necessary.

To my best knowledge they have never been used and route caching
has converted the inp_rt field from that commit to inp_route
rendering this field and these flags obsolete.
Convert the pointer into a spare pointer to not change the size of
the structure anymore (and to have a spare pointer) and mark the
two fields as unused.

The stac/clac combo around each byte copy is causing a measurable

copied. While here reorder the code to avoid a forward branch in

Note the copying loop (originating from copyinstr) is avoidably slow
and will be fixed later.

The receive side scaling stride parameter is a value which define the interval
between active receive side queues. The traffic for the inactive queues is
redirected to the nearest active queue by use of modulus. The default value
of this parameter is one, which means all receive side queues are used.
The point of this feature is to redirect more traffic to fewer receive side
queues in order to take more advantage of sorted large receive offload,
sorted LRO. The sorted LRO works better when more packets are accumulated
per service interval.

Previously a value of 56 DS was used and this would work in the
