This was normal behavior as long as all the devargs come to this driver,

2 years agodoc: strip build artefacts for examples file list

doc: strip build artefacts for examples file list

examples.dox is built inside builddir/doc/api and so doxygen generates
some dir_HASH.html that includes the builddir name and this may prevent
DPDK documentation to be correctly generated in some distributions, for
example CentOS Stream 9 and RHEL9, since the builddir includes the
architecture.

This commit adds builddir/doc/api (the path where examples.dox is
generated) to STRIP_FROM_PATH, so the generated documentation doesn't
change if builddir changes.

kni: restrict bifurcated device support

To enable bifurcated device support, rtnl_lock is released before calling
userspace callbacks and asynchronous requests are enabled.

But these changes caused more issues, like bug #809, #816. To reduce the
scope of the problems, the bifurcated device support related changes are
only enabled when it is requested explicitly with new 'enable_bifurcated'
module parameter.
And bifurcated device support is disabled by default.

So the bifurcated device related problems are isolated and they can be
fixed without impacting all use cases.
