James Smart 64eb4dcb14 scsi: lpfc: Cleanup entry_repost settings on SLI4 queues
Too many work items being processed in IRQ context take a lot of CPU
time and cause problems.

With a recent change, we get out of the ISR after hitting entry_repost
work items on a queue. However, the actual values for entry repost are
still high. EQ is 128 and CQ is 128, this could translate into
processing 128 * 128 (16384) work items under IRQ context.

Set entry_repost in the actual queue creation routine now.  Limit EQ
repost to 8 and CQ repost to 64 to further limit the amount of time
spent in the IRQ.

Fix fof IRQ routines as well.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
