Yunsheng Lin says: ==================== Some cleanup and bugfix for desc filling When retransmiting packets, skb_cow_head which is called in hns3_set_tso may clone a new header. And driver will clear the checksum of the header after doing DMA map, so HW will read the old header whose L3 checksum is not cleared and calculate a wrong L3 checksum. Also When sending a big fragment using multiple buffer descriptor, hns3 does one maping, but do multiple unmapping when tx is done, which may cause unmapping problem. This patchset does some cleanup before fixing the above problem. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
