Loongson delivers two types of the network devices: Loongson GMAC and Loongson GNET in the framework of four SOC/Chipsets revisions: Chip Network PCI Dev ID Synopys Version DMA-channel LS2K1000 SOC GMAC 0x7a03 v3.50a/v3.73a 1 LS7A1000 Chipset GMAC 0x7a03 v3.50a/v3.73a 1 LS2K2000 SOC GMAC 0x7a03 v3.73a 8 LS2K2000 SOC GNET 0x7a13 v3.73a 8 LS7A2000 Chipset GNET 0x7a13 v3.73a 1 The driver currently supports the chips with the Loongson GMAC network device synthesized with a single DMA-channel available. As a preparation before adding the Loongson GNET support detach the Loongson GMAC-specific platform data initializations to the loongson_gmac_data() method and preserve the common settings in the loongson_default_data(). While at it drop the return value statement from the loongson_default_data() method as redundant. Note there is no intermediate vendor-specific PCS in between the MAC and PHY on Loongson GMAC and GNET. So the plat->mac_interface field can be freely initialized with the PHY_INTERFACE_MODE_NA value.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
