If buffer size is not usb_endpoint_maxp (512 or 1024 bytes) multiple, usb host driver has to use bounce buffer and copy data. For RX we can avoid that since we alreay allocate q->buf_size (2kB) buffers and mt76usb hardware will not fill more data as rx packet size is limited by network protocol. However add error message if this assumption somehow will be not true. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
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.
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.
