Support TX timestamping in L2CAP sockets. Support MSG_ERRQUEUE recvmsg. For other than SOCK_STREAM L2CAP sockets, if a packet from sendmsg() is fragmented, only the first ACL fragment is timestamped. For SOCK_STREAM L2CAP sockets, use the bytestream convention and timestamp the last fragment and count bytes in tskey. Timestamps are not generated in the Enhanced Retransmission mode, as meaning of COMPLETION stamp is unclear if L2CAP layer retransmits.

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.
