Device Performance Enhancements
Netconf is a yearly, by-invitation-only, Linux community conference running for the third year. The agenda has a clear focus on kernel level networking. Attendees are the main maintainers and developers of the Linux networking subsystem. Invitation is issued only 10-15 people who have provided significant contributions.
For more information see the conference sites:
NAPI ("New API") is an extension to the device driver packet processing framework, which is designed to improve the performance of high-speed networking. NAPI works through:
TCP testing in Linux is an continuous process. These tests are concerned with the behavior and correctness of the TCP protocol in the Linux kernel.
More will be added to this page soon.
Linux has the most RFC compliant TCP implementation. Over time this page will have more details on it's implementation and areas such as congestion control.
Linux packet generator is a tool to generate packets at very high speed
in the kernel.
This document gives a brief introduction to Generic Netlink, some simple
examples on how to use it and some recommendations on how to make the most of
the Generic Netlink communications interface. While this document does not
require that the reader has a detailed understanding of what Netlink is
and how it works, some basic Netlink knowledge is assumed. As usual, the
kernel source code is your best friend here.
Netlink is a flexible, robust, wire-format communications channel typically used for kernel to user communication although it can also be used for user to user and kernel to kernel communications.
Wireless networking in Linux is really easy to use. The wireless-tools allow to explore and configure wireless network.

Please ignore my following comment, I didn't see you already have mentioned the VLAN accelaration part...
regarding the last section, I haven't checked 2.6 kernel, but in 2.4 kernel, it does not like that it is always the case you replace net_if_rx() with vlan_hwaccel_rx(), in fact, seems to me only those interfaces support "hardware accelaration" uses the latter.
What was the purpose of this last edit, 00:18, 18 April 2007 by JyqXan, it seems to remove large chunks of the text for no apparent reason? Unless JyqXan has an explanation I propose we revert the latest change.
There are a few of these random mutilations going on by randomly named users. No idea why! I think I might have accidentaly marked this as patrolled but don't know how to reverse. User:Imcdnzl
Okay, thanks both for the explanation and the fix.
