[PATCH net-next 0/3] net: hns3: enhance capabilities for fibre port

[Peng Li]

From: Jian Shen <shenjian15@huawei.com>

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

[PATCH net-next 1/3] net: hns3: add support for multiple media type

[Peng Li]

From: Jian Shen <shenjian15@huawei.com>

Previously, we can only identify copper and fiber type, the
supported link modes of port information are always showing
SR type. This patch adds support for multiple media types,
include SR, LR CR, KR. Driver needs to query the media type
from firmware periodicly, and updates the port information.

The new port information looks like this:
Settings for eth0:
        Supported ports: [ FIBRE ]
        Supported link modes:   25000baseCR/Full
                                25000baseSR/Full
                                1000baseX/Full
                                10000baseCR/Full
                                10000baseSR/Full
                                10000baseLR/Full
        Supported pause frame use: Symmetric
        Supports auto-negotiation: No
        Supported FEC modes: None BaseR
        Advertised link modes:  25000baseCR/Full
                                25000baseSR/Full
                                1000baseX/Full
                                10000baseCR/Full
                                10000baseSR/Full
                                10000baseLR/Full
        Advertised pause frame use: Symmetric
        Advertised auto-negotiation: No
        Advertised FEC modes: None BaseR
        Speed: 10000Mb/s
        Duplex: Full
        Port: FIBRE
        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: off
        Current message level: 0x00000036 (54)
                               probe link ifdown ifup
        Link detected: yes

In order to be compatible with old firmware which only support
sfp speed, we remained using the same query command, and kept
the former logic.

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

[Peng Li]

From: Jian Shen <shenjian15@huawei.com>

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.

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

[Peng Li]

From: Jian Shen <shenjian15@huawei.com>

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.

Hi Peng

If it does not support auto-negotiation, do these advertised link
modes make any sense? Does it really advertise, or is it all fixed
configured?

Hi Andrew:

it makes no sense when auto-negotiation is not supported.
I should handle it differently with the case supports auto-negotiation
and not supports auto-negotiation.

I will fix it in next version, result like below:
Settings for eth0:
         Supported ports: [ FIBRE ]
         Supported link modes:   25000baseCR/Full
                                 25000baseSR/Full
                                 1000baseX/Full
                                 10000baseCR/Full
                                 10000baseSR/Full
                                 10000baseLR/Full
         Supported pause frame use: Symmetric
         Supports auto-negotiation: No
         Supported FEC modes: None BaseR
         Advertised link modes:  Not reported
         Advertised pause frame use: No
         Advertised auto-negotiation: No
         Advertised FEC modes: Not reported
         Speed: 10000Mb/s
         Duplex: Full
         Port: FIBRE
         PHYAD: 0
         Transceiver: internal
         Auto-negotiation: off
         Current message level: 0x00000036 (54)
                                probe link ifdown ifup
         Link detected: yes

         Wish I have understood your comments correctly.


Thanks!

Hi, Andrew:
Thanks for your review. And I have replied your comments.

As this week is 5.1-rc7,  not sure if there is rc8,
I'm sorry for sending V2 patch-set
without waiting for your reply again on V1.

Thanks
