skb_tx_timestamp() is used for tx software timestamp enabled by SOF_TIMESTAMPING_TX_SOFTWARE while SKBTX_HW_TSTAMP is used for SOF_TIMESTAMPING_TX_HARDWARE. As it clearly shows they are different timestamps in two dimensions, it's not appropriate to group these two together in the if-statement. This patch completes three things: 1. make the software one standalone. Users are able to set both timestamps together with SOF_TIMESTAMPING_OPT_TX_SWHW flag. 2. make the software one generated after the hardware timestamp logic to avoid generating sw and hw timestamps at one time without SOF_TIMESTAMPING_OPT_TX_SWHW being set. 3. move the software timestamp call as close to the door bell.

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.
