cxgb4: fix more warnings reported by sparse
Patch 1 ensures all callers take on-chip memory lock when flashing
PHY firmware to fix lock context imbalance warnings.
Patch 2 moves all static arrays in header file to respective C file

Move all arrays related to device dump in header file to C file.
Also, move the function that shares the arrays to the same C file.

Two phylink pause fixes
While testing, I discovered two issues with ethtool -A with phylink.
First, if there is a PHY bound to the network device, we hit a
deadlock when phylib tries to notify us of the link changing as a
result of triggering a renegotiation.
Second, when we are manually forcing the pause settings, and there
is no renegotiation triggered, we do not update the MAC via the new
mac_link_up approach.
These two patches solve both problems, and will need to be backported
to v5.7; they do not apply cleanly there due to the introduction of
PCS in the v5.8 merge window.

We have been relying on link events and mac_config() when the manual
pause modes are changed. With recent developments, such as moving
the programming of link state to mac_link_up(), this no longer works.
To ensure that we update the MAC, we must generate a link-down followed
by a link-up event; we can do that by setting mac_link_dropped and
triggering a resolve.

Clearing the sock TX queue in sk_set_socket() might cause unexpected
out-of-order transmit when called from sock_orphan(), as outstanding
packets can pick a different TX queue and bypass the ones already queued.
This is undesired in general. More specifically, it breaks the in-order
scheduling property guarantee for device-offloaded TLS sockets.

Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add
new rxtimestamp.sh wrapper script, so that the test runs isolated
from background traffic in a private network namespace.
Also ignore failures of test case #6 by default. This case verifies
that a receive timestamp is not reported if timestamp reporting is
enabled for a socket, but generation is disabled. Receive timestamp
generation has to be enabled globally, as no associated socket is
known yet. A background process that enables rx timestamp generation
therefore causes a false positive. Ntpd is one example that does.
Add a "--strict" option to cause failure in the event that any test
case fails, including test #6. This is useful for environments that
are known to not have such background processes.

The mdiobus_scan logic is currently hardcoded to only
work with c22 devices. This works fairly well in most
cases, but its possible that a c45 device doesn't respond
despite being a standard phy. If the parent hardware
is capable, it makes sense to scan for c22 devices before
falling back to c45.
As we want this to reflect the capabilities of the STA,
lets add a field to the mii_bus structure to represent
the capability. That way devices can opt into the extended
scanning. Existing users should continue to default to c22
only scanning as long as they are zero'ing the structure
before use.

On older firmware, the hardware statistics are not cleared when the
driver frees the hardware stats contexts during ifdown. The driver
expects these stats to be cleared and saves a copy before freeing
the stats contexts. During the next ifup, the driver will likely
allocate the same hardware stats contexts and this will cause a big
increase in the counters as the old counters are added back to the
saved counters.
We fix it by making an additional firmware call to clear the counters
before freeing the hw stats contexts when the firmware is the older
20.x firmware.

Fix boottime kprobe events to report and abort after each failure when

As an example, when we try to set multiprobe kprobe events in
bootconfig like this:
ftrace.event.kprobes.vfsevents {
probes = "vfs_read $arg1 $arg2,,
!error! not reported;?", // leads to error
"vfs_write $arg1 $arg2"
}
This will not work as expected. After
commit da0f1f4167 ("tracing/boottime: Fix kprobe event API usage"),
the function trace_boot_add_kprobe_event will not produce any error
message when adding a probe fails at kprobe_event_gen_cmd_start.
Furthermore, we continue to add probes when kprobe_event_gen_cmd_end fails
(and kprobe_event_gen_cmd_start did not fail). In this case the function
even returns successfully when the last call to kprobe_event_gen_cmd_end
is successful.
The behaviour of reporting and aborting after failures is not
consistent.
The function trace_boot_add_kprobe_event now reports each failure and
stops adding probes immediately.

Remove the set but unused variable when DCB is disabled. Instead,
do the calculation directly inline.
Fixes following warning in make W=1:
cxgb4_main.c: In function 'cfg_queues':
cxgb4_main.c:5380:29: warning: variable 'n1g' set but not used
[-Wunused-but-set-variable]
