Description

When ls1046a is connected to 10G Copper Ethernet, it links up with 100Mbps speed, not 10Gbps.

If the customer modifies kernel-source/drivers/net/phy/aquantia_main.c like below, the link is up with 10Gbps speed.

kernel-source/drivers/net/phy/aquantia_main.c

static int aqr_config_aneg(struct phy_device *phydev)
{
int ret = 0;
+ return ret;
linkmode_copy(phydev->supported, phy_10gbit_features);

Steps to Reproduce

1. configure and build wrlinux image

$ ./wrlinux-x/setup.sh --machines nxp-ls1046 --templates feature/bsp-extras --dl-layers
$ bitbake wrlinux-image-std
2. boot the wrlinux image

3. connect eth4 to 10G Copper port on another target.

4. link up on target

root@nxp-ls1046:~# ip link set eth4 up
root@nxp-ls1046:~# ifconfig eth4 10.20.0.11
5. cheeck the "Speed" entry: it indicates "100Mb/s".

root@nxp-ls1046:~# ethtool eth4
Settings for eth4:
        Supported ports: [ TP AUI BNC MII FIBRE Backplane ]
        Supported link modes:   10baseT/Half 10baseT/Full

        Link detected: yes
 

6. modify kernel-source/drivers/net/phy/aquantia_main.c

static int aqr_config_aneg(struct phy_device *phydev)
{
int ret = 0;
+ return ret;
linkmode_copy(phydev->supported, phy_10gbit_features);
7. build kernel again
 8. boot the kernel
 9. check the link speed again (The "Speed" is "10000Mb/s")

# ip link set eth4 up
# ethtool eth4
