FUJITA Tomonori says: ==================== add ethernet driver for Tehuti Networks TN40xx chips This patchset adds a new 10G ethernet driver for Tehuti Networks TN40xx chips. Note in mainline, there is a driver for Tehuti Networks (drivers/net/ethernet/tehuti/tehuti.[hc]), which supports TN30xx chips. Multiple vendors (DLink, Asus, Edimax, QNAP, etc) developed adapters based on TN40xx chips. Tehuti Networks went out of business but the drivers are still distributed under GPL2 with some of the hardware (and also available on some sites). With some changes, I try to upstream this driver with a new PHY driver in Rust. The major change is replacing the PHY abstraction layer in the original driver with phylink. TN40xx chips are used with various PHY hardware (AMCC QT2025, TI TLK10232, Aqrate AQR105, and Marvell MV88X3120, MV88X3310, and MV88E2010). I've also been working on a new PHY driver for QT2025 in Rust [1]. For now, I enable only adapters using QT2025 PHY in the PCI ID table of this driver. I've tested this driver and the QT2025 PHY driver with Edimax EN-9320 10G adapter and 10G-SR SFP+. In mainline, there are PHY drivers for AQR105 and Marvell PHYs, which could work for some TN40xx adapters with this driver. To make reviewing easier, this patchset has only basic functions. Once merged, I'll submit features like ethtool support. v11: https://lore.kernel.org/netdev/20240618051608.95208-7-fujita.tomonori@gmail.com/ v10: https://lore.kernel.org/netdev/20240611045217.78529-7-fujita.tomonori@gmail.com/ v9: https://lore.kernel.org/netdev/20240605232608.65471-1-fujita.tomonori@gmail.com/ v8: https://lore.kernel.org/netdev/20240603064955.58327-1-fujita.tomonori@gmail.com/ v7: https://lore.kernel.org/netdev/20240527203928.38206-7-fujita.tomonori@gmail.com/ v6: https://lore.kernel.org/netdev/20240512085611.79747-2-fujita.tomonori@gmail.com/ v5: https://lore.kernel.org/netdev/20240508113947.68530-1-fujita.tomonori@gmail.com/ v4: https://lore.kernel.org/netdev/20240501230552.53185-1-fujita.tomonori@gmail.com/ v3: https://lore.kernel.org/netdev/20240429043827.44407-1-fujita.tomonori@gmail.com/ v2: https://lore.kernel.org/netdev/20240425010354.32605-1-fujita.tomonori@gmail.com/ v1: https://lore.kernel.org/netdev/20240415104352.4685-1-fujita.tomonori@gmail.com/ [1] https://lore.kernel.org/netdev/20240415104701.4772-1-fujita.tomonori@gmail.com/ ==================== Link: https://patch.msgid.link/20240623235507.108147-1-fujita.tomonori@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
