We currently have a fair number of working drivers that cover most of the available WNICs on the market. However, most don't implement all possible features and many have issues. Hardware by companies not providing complete specifications, free firmware and drivers can be more problematic to support. The switching of chipsets by manufacturers without changing model numbers also makes this list less useful to those purchasing new hardware. Except for a handful of WNICs with free software drivers and free firmware, like e.g. the Penguin 802.11N, most available wireless hardware can not be exhausted when used with Linux. Below is an alphabetically sorted list of existent Linux drivers and their current capabilities.

Driver developers/printer manufacturers: you may upload printer drivers directly through our website to have them included on our download pages as well as repositories for Linux distros. Register for a LinuxFoundation.org account and contact the OpenPrinting staff to enable this feature. NI Linux Device Drivers software provides Linux Desktop support for a variety of NI test and measurement hardware. It offers a repository add-on that you can download to instruct your Linux distribution’s native package manager to install NI driver software packages such as NI-DAQmx, NI-VISA, NI-488.2, and NI-Sync. A set of drivers that enable synthetic device support in supported Linux virtual machines under Hyper-V. See the Details section of this page for a link to more information about the latest Linux Integration Services (LIS) availability and supported distributions. Contain hardware compatibility for each Linux distribution (for all current and newer systems). There are various methods to install Brother Linux Drivers. The Driver Install Tool allows you to download one file to install printer drivers and scanner drivers for compatible models. Network users must first connect your machine to your network before installing the software. Refer to the steps based on your connection method.

NOTE: All drivers can of course run in station mode, but only a few drivers support the other available wireless modes! Support of cfg80211 also offers benefits.

Note: **staging drivers

Notes:

802.11a capabilities depend on the actual radio chip used.
802.11a devices exist, but currently can't be used with this driver, A/B/G devices will work in B/G mode only.
There is support with a special, out-of-tree driver and special firmware, see http://sf.net/projects/ipw2200-ap.
Slightly different mesh implementation than mac80211's, in firmware.
Tested with RT2870/RT3070 driver

The Linux NVMe™ driver is open source and included as part of the Linux Kernel, which can be found here https://github.com/torvalds/linux/tree/master/drivers/nvme

NVMe architecture works out of the box in every major operating system, including all mainstream Linux distributions. Please check on specific feature support with the distros, e.g. Red Hat Enterprise Linux, Ubuntu. NVMe technology has been supported since kernel 3.3, and at the time had been backported to 2.6. Intel released some history of the Linux NVMe drivers stack in 2015 here:

Overviews of the Linux NVMe driver stack can be found here:

For latest updates including Kernel 5.3:

For updates up to Kernel 4.13:

Open Source Management Utility – NVMe Command Line Interface (NVMe-CLI)

Linux Driver Download Page

The tool to manage NVMe SSDs in Linux is called NVMe-CLI, https://github.com/linux-nvme/nvme-cli

Data centers require many management functions to monitor the health of the SSD, monitor endurance, update firmware, securely erase storage, and read various logs. This tool matches the NVMe specification for command structure. You will notice the commands available in NVMe-CLI match the specification. You will need the latest NVMe 1.4 specification to be able to interpret the abbreviations for the various commands, found here:

For instance, in section 5.15.3 Identify Controller data structure, you can send the command nvme-id-ctrl in NVMe-CLI. The output will have abbreviations for the various fields, for instance, Model Number (MN) is displayed in NVMe-CLI as mn.

NVMe-CLI can be obtained as a package for all the Linux distributions.
