Testing the NPIV Login response capabilities is a long winded process of dereferencing the vhost->login_buf->resp.capabilities field, then byte swapping that value to host endian, and performing the bitwise test. Currently we only ever check this in ibmvfc_cancel_all(), but follow-up patches will need to regularly check for targetWWPN and channelization support. Add a helper to simplify checking various VIOS capabilities, namely ibmvfc_check_caps().

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.
