[dpdk-dev] [PATCH V3 07/14] net/hns3: fix device capabilities for copper media type

[Lijun Ou <oulijun@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

The configuration operation for PHY is implemented by firmware. And
a capability flag will be report to driver, which means the firmware
supports the PHY driver.  However, the current implementation only
supports obtaining the capability bit, but some basic functions of
copper ports in driver, such as, the query of link status and link
info, are not supported.

Therefore, it is necessary for driver to set the copper capability
bit to zero when the firmware supports the configuration of the PHY.

Fixes: 438752358158 ("net/hns3: get device capability from firmware")
Fixes: 95e50325864c ("net/hns3: support copper media type")
