The latest SA6400 cannot be driven (installed through the latest RR23.11.6 boot, which already supports the 11th and 12th generation hard solutions, and can also use Sata disks). The platform architecture, Epyc7002, should be due to the fact that the kernel is 5.10. I hope to update it, because currently, only the SA6400 kernel is 5.10 in Black Group Hui, and other systems are ancestral 4.4, which cannot perfectly drive the 11th, 12th, 13th, and 14th generation hard solutions.

• If you want to support S5 WOL, you have to find

  EXTRA_CFLAGS += -DRTL8152_S5_WOL

  in the Makefile. Then, remove the first character '#", if it exists.

• For Fedora, you may have to run the following command after installing the driver.

  dracut -f

• For Ubuntu, you may have to run the following command after installing the driver.

  sudo depmod -a

  sudo update-initramfs -u

• Example of setting speed

  2.5G before kernel v4.10

  ethtool -s eth0 autoneg on advertise 0x802f

  2.5G for kernel v4.10 and later

  ethtool -s eth0 autoneg on advertise 0x80000000002f

  ethtool -s eth0 autoneg on advertise 0x002f (1G)

  ethtool -s eth0 autoneg on advertise 0x000f (100M full)

  ethtool -s eth0 autoneg on advertise 0x0003 (10M full)

• Disable center tap short

  make CONFIG_CTAP_SHORT=OFF modules

• Ring parameter

  Show Ring parameter

  ethtool -g eth0

  Changes the number of ring entries for the Rx ring.

  ethtool -G eth0 rx 100

• Tunable parameters

  Get the current rx copybreak value in bytes.

  ethtool --get-tunable eth0 rx-copybreak

  Set the rx copybreak value in bytes.

  ethtool --set-tunable eth0 rx-copybreak 256

• Flow control

  Queries the specified Ethernet device for pause parameter information.

  ethtool -a eth0

  Changes the pause parameters of the specified Ethernet device.

  ethtool -A eth0 rx off tx off (Disable flow control)

  ethtool -A eth0 rx on tx off (Enable flow control)
