Subject: net/hns3: support copper media type
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=95e50325864c12682eb9872f69ec682be1a688a8;p=dpdk.git

net/hns3: support copper media type

The hns3 network engine is built-in multiple SoCs, such as kunpeng 920,
kunpeng 930, etc. The PCI revision id is 0x21 in kunpeng 920, and the
PCI revision id is 0x30 in kunpeng 930.

Copper media type is supported for hns3 PF device in kunpeng 930 and
later SoCs. The configuration operation for PHY is implemented by
firmware.
