When using taprio offloading together with ETF offloading, configured
like this, for example:
$ tc qdisc replace dev $IFACE parent root handle 100 taprio \
num_tc 4 \
map 2 2 1 0 3 2 2 2 2 2 2 2 2 2 2 2 \
queues 1@0 1@1 1@2 1@3 \
base-time $BASE_TIME \
sched-entry S 01 1000000 \
sched-entry S 0e 1000000 \
flags 0x2
$ tc qdisc replace dev $IFACE parent 100:1 etf \
offload delta 300000 clockid CLOCK_TAI
During enqueue, it works out that the verification added for the
"txtime" assisted mode is run when using taprio + ETF offloading, the
only thing missing is initializing the 'next_txtime' of all the cycle
entries. (if we don't set 'next_txtime' all packets from SO_TXTIME
sockets are dropped)

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.
