Review of the eq coalescing logic showed the code was a bit fragmented. Sometimes it would save/set via an interrupt max value, while in others it would do so via a usdelay. There were also two places changing eq delay, one place that issued mailbox commands, and another that changed via register writes if supported. Clean this up by: - Standardizing the operation of lpfc_modify_hba_eq_delay() routine so that it is always told of a us delay to impose. The routine then chooses the best way to set that - via register or via mbx. - Rather than two value types stored in eq->q_mode (usdelay if change via register, imax if change via mbox) - q_mode always contains usdelay. Before any value change, old vs new value is compared and only if different is a change done. - Revised the dmult calculation. dmult is not set based on overall imax divided by hardware queues - instead imax applies to a single cpu and the value will be replicated to all cpus.

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.
