Linux kernel source tree
5b039241fe
One issue with the original TSO code was that it was working too hard to deal with skb layouts that were never going to show up, such as an skb->data that was longer than a single descriptor's length. The other issue was trying to arrange the fragment dma mapping at the same time as figuring out the descriptors needed. There was just too much going on at the same time. Now we do the dma mapping first, which sets up the buffers with skb->data in buf[0] and the remaining frags in buf[1..n-1]. Next we spread the bufs across the descriptors needed, where each descriptor gets up to mss number of bytes. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.

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.
