Unlike on earlier chips, DMA completion on MT7615 does not imply actually
having sent out any packets.
Since AQL will prevent filling the hardware queues and will only allow more
packets to be passed to the driver after tx completion, it makes much more
sense to schedule the tx tasklet there.
This is also needed for scheduling tx in testmode support

While looking at the ETSI regulatory domain definitions
and a patch, which allows more channels for ath10k, I also
checked the channels allowed for mt76.

ETSI regulations would possibly allow to add channels 32, 68,
96, 144, 169 and 173. IEEE 802.11-2016 defines no operating class
for channels 32, 68 and 96. This leaves us channels 144, 169 and 173,
which are included in this patch.

I tested 169 and 173 with a mt76 based USB dongle (AVM AC 860) and they
worked fine. If I saw that right, these channels are also covered by
register definitions inside the driver.

Channel 144 should also work, but gets disabled by the kernel as of now.

let DSA interfaces use the default min_mtu and max_mtu specified by
ether_setup(). This is more important for min_mtu: since DSA is
Ethernet, the minimum MTU is the same as of any other Ethernet
interface, and definitely not zero. For the max_mtu, we have a callback

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'setup_hw()' (hfcpci.c) GFP_KERNEL can be used
because it is called from the probe function and no lock is taken.
The call chain is:
   hfc_probe()
   --> setup_card()
   --> setup_hw()

When memory is allocated in 'inittiger()' (netjet.c) GFP_ATOMIC must be
used because a spin_lock is taken by the caller (i.e. 'nj_init_card()')
This is also consistent with the other allocations done in the function.

Add tdc to existing kselftest infrastructure so that it can be run with
existing kselftests. TDC now generates objects in objdir/kselftest
without cluttering main objdir, leaves source directory clean, and
installs correctly in kselftest_install, properly adding itself to
run_kselftest.sh script.

Add tc-testing as a target of selftests/Makefile. Create tdc.sh to run
tdc.py targets with correct arguments. To support single target from
selftest/Makefile, combine tc-testing/bpf/Makefile and
tc-testing/Makefile. Move action.c up a directory to tc-testing/.

Tested with:
 make O=/tmp/{objdir} TARGETS="tc-testing" kselftest
 cd /tmp/{objdir}
 cd kselftest
 cd tc-testing
 ./tdc.sh

 make -C tools/testing/selftests/ TARGETS=tc-testing run_tests

 make TARGETS="tc-testing" kselftest
 cd tools/testing/selftests
 ./kselftest_install.sh /tmp/exampledir

 target and net/pmtu.sh then:

This patch adds u64_stats_update_* usage to protect access to 64-bit stats,
where necessary.

This is necessary for per-ring stats, because they are updated by the
driver directly, so there is a possibility for a partial read.

Other stats require no additional protection, e.g.:
 * all MACSec stats are fetched directly from HW (under semaphore);
 * nic/ndev stats (aq_stats_s) are fetched directly from FW (under mutex).
