Even though 'smp_affinity_enable' module parameter is enabled, if the number of online CPUs is bigger than the number of msix vectors enabled on that HBA, then smp affinity settings should be disabled only for this HBA. But currently the smp affinity setting is disabled globally and hence smp affinity will be disabled for subsequent HBAs even though number of msix vectors enabled for this HBA matches the number of online CPU. To fix this, define a per HBA variable smp_affinity_enable. Initially this variable is initialized with smp_affinity_enable module parameter value. If this HBA has less number of msix vectors configured when compared to number of online cpus, then only this HBA's variable smp_affinity_enable is set to zero.

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.
