====================
Cleanup and optimizations to transmit code
Pad small packets to ETH_ZLEN before transmit, cleanup dma sync calls,
add xmit_more functionality and then further remove atomic
variable usage in the prior.
Changes:
V3:
- Stop returning NETDEV_TX_BUSY when ring is full in xmit_patch.
Change to inspect early if next packet can fit in ring instead of
current packet, and stop queue if not.
- Add smp_mb between stopping tx queue and checking if tx queue has
free entries again, in queue full check function to let reflect
IQ process completions that might have happened on other cpus.
- Update small packet padding patch changelog to give more info.
V2: https://lore.kernel.org/all/20231024145119.2366588-1-srasheed@marvell.com/
- Added patch for padding small packets to ETH_ZLEN, part of
optimization patches for transmit code missed out in V1
- Updated changelog to provide more details for dma_sync remove patch
- Updated changelog to use imperative tone in add xmit_more patch

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.
