This package provides backport support for drivers from newer kernels down to older kernels. It currently backports the following subsystems:

• Ethernet
• Wireless
• Bluetooth
• NFC
• ieee802154
• Media
• Regulator

This package provides the latest Linux kernel subsystem enhancements for kernels 3.0 and above.

License

This work is a subset of the Linux kernel as such we keep the kernel's Copyright practice. Some files have their own copyright and in those cases the license is mentioned in the file. All additional work made to building this package is licensed under the GPLv2.

Backporting preference for EXPORT_SYMBOL_GPL() and proprietary drivers

This framework was designed by intent since its inception only for upstream Linux kernel drivers to avoid excuses about the difficulty to support upstream Linux kernel development while also supporting users on older kernels. To ensure the intent is respected currently all symbols that we do work on to backport are exported via EXPORT_SYMBOL_GPL() as we do work to backport them for the supported kernels. By using EXPORT_SYMBOL_GPL() we make it clear that if you use the backported symbols your software is considered derivative works of the Linux kernel.
