[dpdk-dev] [PATCH v3 1/6] net/hns3: delete some unused capabilities

From: Chengwen Feng <fengchengwen at huawei.com>

This patch deletes some unused capabilities, include:
1. Delete some unused firmware capabilities definition, which are:
UDP_GSO, ATR, INT_QL, SIMPLE_BD, TX_PUSH, FEC and PAUSE.
2. Delete some unused driver capabilities definition, which are:
UDP_GSO, TX_PUSH.
3. Also redefine HNS3_DEV_SUPPORT_*  as enum type, and change some of
the values. Note: the HNS3_DEV_SUPPORT_* values is used only inside
the driver, so it's safe to change the values.
