Guangbin Huang 8c1671e0d1 net: hns3: fix get wrong pfc_en when query PFC configuration 
Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.

for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on

To fix this problem, just returns user's PFC config parameter saved in
driver.

README 

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.
