Implement debugfs in MANA driver to be able to view RX,TX,EQ queue
specific attributes and dump their gdma queues.
These dumps can be used by other userspace utilities to improve
debuggability and troubleshooting
Following files are added in debugfs:
/sys/kernel/debug/mana/
|-------------- 1
|--------------- EQs
| |------- eq0
| | |---head
| | |---tail
| | |---eq_dump
| |------- eq1
| .
| .
|
|--------------- adapter-MTU
|--------------- vport0
|------- RX-0
| |---cq_budget
| |---cq_dump
| |---cq_head
| |---cq_tail
| |---rq_head
| |---rq_nbuf
| |---rq_tail
| |---rxq_dump
|------- RX-1
.
.
|------- TX-0
| |---cq_budget
| |---cq_dump
| |---cq_head
| |---cq_tail
| |---sq_head
| |---sq_pend_skb_qlen
| |---sq_tail
| |---txq_dump
|------- TX-1

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.
