controller. L1 has several threshold/timer registers and they seem to require careful tuned parameters to get best performance. Datasheet for L1 is not available to open source driver writers so age(4) focus on stability and correctness of basic Tx/Rx operation. ATM the performance of age(4) is far from optimal which in turn means there are mis-programmed registers or incorrectly configured registers. Currently age(4) supports all known hardware assistance including - MSI support. - TCP Segmentation Offload. - Hardware VLAN tag insertion/stripping. - TCP/UDP checksum offload. - Interrupt moderation. - Hardware statistics counter support. - Jumbo frame support. - WOL support. L1 gigabit ethernet controller is mainly found on ASUS motherboards. Note, it seems that there are other variants of hardware as known as L2(Fast ethernet) and newer gigabit ethernet (AR81xx) from Atheros. These are not supported by age(4) and requires a seperate driver. Big thanks to all people who reported feedback or tested patches.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
