Yun Lu says: ==================== fix two issues and optimize code on tpacket_snd() This series fix two issues and optimize the code on tpacket_snd(): 1, fix the SO_SNDTIMEO constraint not effective due to the changes in commit 581073f626e3; 2, fix a soft lockup issue on a specific edge case, and also optimize the loop logic to be clearer and more obvious; --- Changes in v5: - Still combine fix and optimization together, change to while(1).

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.
