rx_lanes and tx_lanes sysfs entries show the number of lanes in use by a device. USB 3.2 adds support for Dual-lane (symmetrical), using 2 rx lanes and 2 tx lanes for normal non Inter-Chip SSIC devices. USB 3.1 and older are all single lane. SSIC devices can have up to 4 lanes per direction in use, with different number of rx and tx lanes.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
