Add a very simple test to make sure drivers report expected
stats. Drivers which implement FEC or pause configuration
should report relevant stats. Qstats must be reported,
at least packet and byte counts, and they must match
total device stats.
Tested with netdevsim, bnxt, in-tree and installed.
Add drivers/net as a target for mixed-use tests.
The setup is expected to work similarly to the forwarding tests.
Since we only need one interface (unlike forwarding tests)
read the target device name from NETIF. If not present we'll
try to run the test against netdevsim.

Real devices should implement qstats. Devices which support
pause or FEC configuration should also report the relevant stats.
nsim was missing FEC stats completely, some of the qstats
and pause stats required toggling a debugfs knob.
Note that the tests which used pause always initialize the sett

When interfacing with the ethtool commands it's handy to
be able to use the names of the flags. Example:

"flags": {'stats'}}})
Note that not all commands accept all the flags,
but the meaning of the bits doe
Currently the options for writing networking tests are C, bash or
some mix of the two. YAML/Netlink gives us the ability to easily
interface with Netlink in higher level laguages. In particular,
there is a Python library already available in tree, under tools/net.

By default, HLT instruction executed by guest is intercepted by hypervisor.
However, KVM_CAP_X86_DISABLE_EXITS capability can be used to not intercept
HLT by setting KVM_X86_DISABLE_EXITS_HLT.
Add a test case to test KVM_X86_DISABLE_EXITS_HLT functionality.

Since commit 3a5a6d0c2b03("cpuset: don't nest cgroup_mutex inside
get_online_cpus()"), cpuset hotplug was done asynchronously via a work
function. This is to avoid recursive locking of cgroup_mutex.
Since then, the cgroup locking scheme has changed quite a bit. A
cpuset_mutex was introduced to pro
Add a simple test to verify that an empty v1 cpuset will force its tasks
to be moved to an ancestor node. It is based on the test case documented
in commit 76bb5ab8f6e3 ("cpuset: break kernfs active protection in

As discussed in the LKML thread [1], the asynchronous nature of cpuset
hotplug handling code is causing problem with RCU testing. With recent
changes in the way locking is being handled in the cpuset code, it is
now possible to make the cpuset hotplug code synchronous again without
major changes.
Move test_dev_cgroup.c to prog_tests/dev_cgroup.c to be able to run it
with test_progs. Replace dev_cgroup.bpf.o with skel header file,
