A range of MSIX vectors are allocated at initialization for the number needed for RocE and L2. During run-time, if the user increases or decreases the number of L2 rings, all the MSIX vectors have to be freed and a new range has to be allocated. This is not optimal and causes disruptions to RoCE traffic every time there is a change in L2 MSIX. If the system supports dynamic MSIX allocations, use dynamic allocation to add new L2 MSIX vectors or free unneeded L2 MSIX vectors. RoCE traffic is not affected using this scheme.

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 reStructuredText 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.
