Currently packet_pick_tx_queue() is the only caller of ndo_select_queue() using a fallback argument other than netdev_pick_tx. Leveraging rx queue, we can obtain a similar queue selection behavior using core helpers. After this change, ndo_select_queue() is always invoked with netdev_pick_tx() as fallback. We can change ndo_select_queue() signature in a followup patch, dropping an indirect call per transmitted packet in some scenarios (e.g. TCP syn and XDP generic xmit) This changes slightly how af packet queue selection happens when PACKET_QDISC_BYPASS is set. It's now more similar to plan dev_queue_xmit() tacking in account both XPS and TC mapping. v1 -> v2: - rebased after helper name change RFC -> v1: - initialize sender_cpu to the expected value Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
