From: Jian Shen <[email protected]>

This patchset enhances more capabilities for fibre port,
include multipe media type identification, autoneg,
change port speed and FEC encoding.

Jian Shen (3):
net: hns3: add support for multiple media type
net: hns3: add autoneg and change speed support for fibre port
net: hns3: add support for FEC encoding control

Change log:
V1->V2: fixes comments from Andrew Lunn.

Subject: [PATCH V2 net-next 3/3] net: hns3: add support for FEC encoding control

From: Jian Shen <[email protected]>

This patch adds support for FEC encoding control, user can change
FEC mode by command ethtool --set-fec, and get FEC mode by command
ethtool --show-fec. The fec capability is changed follow the port
speed. If autoneg on, the user configure fec mode will be overwritten
by autoneg result.

Subject: [PATCH V2 net-next 2/3] net: hns3: add autoneg and change speed support for fibre port

From: Jian Shen <[email protected]>

Previously, our driver only supports phydev to autoneg or change
port speed. This patch adds support for fibre port, driver gets
media speed capability and autoneg capability from firmware. If
the media supports multiple speeds, user can change port speed
with command "ethtool -s <devname> speed xxxx autoneg off duplex
full". If autoneg on, the user configuration may be overwritten
by the autoneg result.
