This can be used for calibration in the manufacturing process. It supports sending a configurable number of packets with a specific rate and configurable tx power levels / antenna settings. It also supports receiving packets and showing some statistics, including packet counters and detailed RSSI information.

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 Signed-off-by: -

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. Signed-off-by:

Now that DSA supports MTU configuration, undo the effects of commit 8b1efc0f ("net: remove MTU limits on a few ether_setup callers") and 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 through which drivers can override that, if they want to. Signed-off-by:

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 My VM doesn't run all the kselftests so I commented out all except my target and net/pmtu.sh then: cd /tmp/exampledir && ./run_kselftest.sh Co-developed-by:Davide Caratti <dcaratti@redhat.com> Signed-off-by:
