IPvlan checks if the master device is already used by checking a
specific device (here it's macvlan device). This is technically not
sufficient and it should just ensure the rx_handler is busy or not.
This would be a super check that includes macvlan and any other that
has already registered rx-handler.

gcc-7 and probably earlier versions get confused by this function
and print a harmless warning:
drivers/net/ethernet/broadcom/bcm63xx_enet.c: In function 'bcm_enet_open':
drivers/net/ethernet/broadcom/bcm63xx_enet.c:1130:3: error: 'phydev' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This adds an initialization for the 'phydev' variable when it is unused
and changes the check to test for that NULL pointer to make it clear
that we always pass a valid pointer here.

struct qed_ll2_info is rather large, so putting it on the stack
can cause an overflow, as this warning tries to tell us:
drivers/net/ethernet/qlogic/qed/qed_ll2.c: In function 'qed_ll2_start':
drivers/net/ethernet/qlogic/qed/qed_ll2.c:2159:1: error: the frame size of 1056 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
qed_ll2_start_ooo() already uses a dynamic allocation for the structure
to work around that problem, and we could do the same in qed_ll2_start()
as well as qed_roce_ll2_start(), but since the structure is only
used to pass a couple of initialization values here, it seems nicer
to replace it with a different structure.
Lacking any idea for better naming, I'm adding 'struct qed_ll2_conn',
which now contains all the initialization data, and this now simply
gets copied into struct qed_ll2_info rather than assigning all members
one by one.

These drivers use a set of complicated macros to extract and insert
information for the RX and TX descriptors. Driver rtl8192cu had a
different set than was used for the PCI-based drivers. To simplify
the code, rtl8192cu is switched to use the common version. In the
process, two errors in those common macros were found and fixed.
Besides simplifying the code, there is an additional benefit. We have
no BE hardware to test the PCI driver, but using the common macros
provides an additional test for the validity of many endian-sensitive
operations.

This driver requires a checksum for the descriptors so that the wifi
chip is assured that the USB transmission was correct. These entries
are little-endian, but the driver was always using cpu order in the
calculation. As a result, the driver failed on BE hardware.

The firmware is read from disk as a little-endian byte string. The code
that loads the firmware into the device transfers it as 4-byte quantities.
The routines that write multi-byte quantities on BE hardware assume that
the data are in CPU order, and automatically do the conversion to the LE
order required by the device. As a result, the firmware is transmitted
incorrectly. Rather than do multiple byte swaps on the data, the download
routine is revised to transmit bytes rather than dwords. Although the
number of I/O operations is increased, the firmware is not often loaded.
All drivers have the same bug, and use essentially the same code to
download firmware. These routines have been moved into rtlwifi.
Some CamelCase variables have been renamed.

The debugging macros contain a parameter COMP_XX that could be used as a
mask; however, the code turns all these various bits on at the same time.
This change implements them as a proper mask, and adds module parameters
to set the mask at load time.
The current name "debug" for the debug level has been changed to
"debug_level" to better differentiate it from "debug_mask".
The debug routines have also been changed to interrogate the structure
that is loaded at entry time. As a result, the structure rtl_debug is no
longer needed, and all references to it are deleted.

brcmf_sdio_fromevntchan() was being called on the the data frame
rather than the software header, causing some frames to be
mischaracterized as on the event channel rather than the data channel.
This fixes a major performance regression (due to dropped packets). With
this patch the download speed jumped from 1Mbit/s back up to 40MBit/s due
to the sheer amount of packets being incorrectly processed.

Marvell folks tell me this is a debugging event that the driver doesn't
need to handle, but on 8997 w/ firmware 16.68.1.p97, I see several of

In mwifiex_delay_for_sleep_cookie(), we're looping and waiting for the
PCIe endpoint to write a magic value back to memory, to signal that it
has finished going to sleep. We're not letting the compiler know that
this might change underneath our feet though. Let's do that, for good
hygiene.
I'm not aware of this fixing any concrete problems. I also give no
guarantee that this loop is actually correct in any other way, but at
least this looks like an improvement to me.

The following sequence occurs when using IEEE power-save on 8997:
(a) driver sees SLEEP event
(b) driver issues SLEEP CONFIRM
(c) driver recevies CMD interrupt; within the interrupt processing loop,
we do (d) and (e):
(d) wait for FW sleep cookie (and often time out; it takes a while), FW
is putting card into low power mode
(e) re-check PCIE_HOST_INT_STATUS register; quit loop with 0 value
But at (e), no one actually signaled an interrupt (i.e., we didn't check
adapter->int_status). And what's more, because the card is going to
sleep, this register read appears to take a very long time in some cases
-- 3 milliseconds in my case!
Now, I propose that (e) is completely unnecessary. If there were any
additional interrupts signaled after the start of this loop, then the
interrupt handler would have set adapter->int_status to non-zero and
queued more work for the main loop -- and we'd catch it on the next
iteration of the main loop.
So this patch drops all the looping/re-reading of PCIE_HOST_INT_STATUS,
which avoids the problematic (and slow) register read in step (e).
Incidentally, this is a very similar issue to the one fixed in commit
ec815dd2a5f1 ("mwifiex: prevent register accesses after host is
sleeping"), except that the register read is just very slow instead of
fatal in this case.
Tested on 8997 in both MSI and (though not technically supported at the
moment) MSI-X mode.

Depending on system factors (e.g., the PCIe link PM state), the first
read to wake up the Wifi firmware can take a long time. There is no
reason to use a (blocking, non-posted) read at this point, so let's just
use a write instead. Write vs. read doesn't matter functionality-wise --
it's just a dummy operation. But let's make sure to re-write with the
correct "ready" signature, since we check for that in other parts of the
driver.
This has been shown to decrease the time spent blocking in this function
on RK3399.

Commit 04aeb56a1732 ("net/mlx4_en: allocate non 0-order pages for RX
ring with __GFP_NOMEMALLOC") added code that appears to be not needed at
that time, since mlx4 never used __GFP_MEMALLOC allocations anyway.
As using memory reserves is a must in some situations (swap over NFS or
iSCSI), this patch adds this flag.
Note that this driver does not reuse pages (yet) so we do not have to
add anything else.

Not clearing the previous tx bit rate status
results in a ambigous tx bit rate reporting to
mac80211/cfg80211, for example the previous bit
rate status would have been marked as legacy rate
, while the current rate would have been an HT/VHT
rate with the tx bit rate flags set and this results
in exporting tx bitrate as legacy rate but with HT/VHT
rate flags set, fix this by clearing the tx bitrate
status for each event. This also fixes the below
warning when we do:
iw dev wlan#N station dump

Station pointers are RCU protected so driver must
be extra careful if it tries to store them
internally for later use outside of the RCU
section it obtained it in.
It was possible for station teardown to race with
some htt events. The possible outcome could be a
use-after-free and a crash.
Only peer-flow-control capable firmware was
affected (so hardware-wise qca99x0 and qca4019).
This could be done in sta_state() itself via
explicit synchronize_net() call but there's
already a convenient sta_pre_rcu_remove() op that
can be hooked up to avoid extra rcu stall.
The peer->sta pointer itself can't be set to
NULL/ERR_PTR because it is later used in
sta_state() for extra sanity checks.
