Downstream patches will add support for lag over 4 ports. In that mode we will only use hash as the uplink selection method. Using hash instead of queue affinity (before this patch) offers key advantages like: - Align ports selection method with the method used by the bond device - Better packets distribution where a single queue can transmit from multiple ports (with queue affinity a queue is bound to a single port regardless of the packet being sent). - In case of failover we traffic is split between multiple ports and not a single one like in queue affinity. Going forward it was decided that queue affinity will be deprecated as using hash provides a better user experience which means on 4 ports HCAs hash will always be used. Future work will add hash support for 2 ports HCAs as well.

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.
