[dpdk-dev] [PATCH 01/11] net/hns3: get device capability from firmware

["Wei Hu (Xavier)" <huwei013@chinasoftinc.com>]

From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

This patch adds getting device capabilities from firmware, so driver can
supply differnet cpabilities and specifications to upper level
applications base on differnet versions of hardware network engine.
