Subject: [PATCH v2 net-next 00/10] Add support for DCB feature in hns3 driver

The patchset contains some enhancement related to DCB before
adding support for DCB feature.

This patchset depends on the following patchset:
https://patchwork.ozlabs.org/cover/815646/
https://patchwork.ozlabs.org/cover/816145/

High Level Architecture:

       [ tc qdisc ]	       [ lldpad ]
             |                     |
             |                     |
             |                     |
       [ hns3_enet ]        [ hns3_dcbnl ]
             \                    /
                \              /
                   \        /
                 [ hclge_dcb ]
                   /      \
                /            \
             /                  \
     [ hclge_main ]        [ hclge_tm ]

Current patch-set support following functionality:
1. Use of tc qdisc to configure the tc num and prio_tc_map.
2. Use of lldptool to configure the tc schedule mode, tc
   bandwidth(if schedule mode is ETS), prio_tc_map and
   PFC parameter.
