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.

qeth has been supporting multiple HW Output Queues for a long time. But rather than exposing those queues to the stack, it uses its own queue selection logic in .ndo_start_xmit... with all the drawbacks that entails. Start off by switching IQD devices over to a proper mqs net_device, and converting all the netdev_queue management code. One oddity with IQD devices is the requirement to place all mcast traffic on the _highest_ established HW queue. Doing so via .ndo_select_queue seems straight-forward - but that won't work if only some of the HW queues are active (ie. when dev->real_num_tx_queues < dev->num_tx_queues), since netdev_cap_txqueue() will not allow us to put skbs on the higher queues. To make this work, we 1. let .ndo_select_queue() map all mcast traffic to netdev_queue 0, and 2. later re-map the netdev_queue and HW queue indices in .ndo_start_xmit and the TX completion handler. With this patch we default to a fixed set of 1 ucast and 1 mcast queue. Support for dynamic reconfiguration is added at a later time. Signed-off-by:Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by:
