Abhishek Pandit-Subedi 7fedd3bb6b Bluetooth: Prioritize SCO traffic
When scheduling TX packets, send all SCO/eSCO packets first, check for
pending SCO/eSCO packets after every ACL/LE packet and send them if any
are pending.  This is done to make sure that we can meet SCO deadlines
on slow interfaces like UART.

If we were to queue up multiple ACL packets without checking for a SCO
packet, we might miss the SCO timing. For example:

The time it takes to send a maximum size ACL packet (1024 bytes):
t = 10/8 * 1024 bytes * 8 bits/byte * 1 packet / baudrate
        where 10/8 is uart overhead due to start/stop bits per byte

Replace t = 3.75ms (SCO deadline), which gives us a baudrate of 2730666.

At a baudrate of 3000000, if we didn't check for SCO packets within 1024
bytes, we would miss the 3.75ms timing window.

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.
