@ -5,3 +5,17 @@ This table contains a list of all available native drivers,
depending on the kernel version.
The `generic` and the `ccat` driver are independent of the kernel version.
To find out which native driver is required for your network card,
you can use `lspci -vv` or look in `/sys`:
```sh
admin@ipc:~> ls -l /sys/class/net/eth5/device/driver
lrwxrwxrwx 1 root root 0 6. Nov 15:35 /sys/class/net/eth5/device/driver -> ../../../../bus/pci/drivers/e1000
```
or
```sh
admin@ipc:~> basename $(readlink /sys/class/net/eth5/device/driver)
e1000
```
In this example, `eth5` uses the `e1000` driver.

* meaning of the phy_interface_mode values to something that the PHY
* driver will interpret and act on such that we have two mistakes
* canceling themselves so to speak. We only do this for the two
* modes that GENET driver officially supports on Broadcom STB chips:
* PHY_INTERFACE_MODE_RGMII and PHY_INTERFACE_MODE_RGMII_TXID. Other
* modes are not *officially* supported with the boot loader and the
* scripted environment generating Device Tree blobs for those
* platforms.
*
* Note that internal PHY, MoCA and fixed-link configurations are not
* affected because they use different phy_interface_t values or the
* Generic PHY driver.
