o s/printf/device_printf/g o Nuke OpenBSDism. o Nuke NetBSD/OpenBSD specific DMA sync operations.(we don't have a way to sync a single descriptor within a DMA map.) o Remove recursive mutex. o bus_dma(9) clean up. o 40bit DMA address support. o Add protection for Rx map load failure. o Fix a long standing bug for watchdog timeout. [1] o Add additional protections, missing Tx completion interrupt, losing start Tx command, for watchdog timeout. o Switch to taskqueue(9) API to handle interrupts. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Advertise VLAN header length/capability correctly to upper layer. o Remove excessive kernel stack consumption in nfe_encap(). o Handle highly fragmented mbuf chains correctly. o Enable etherenet address reprogramming with ifconfig(8). o Add ALTQ/TSO, MSI/MSIX support. o Increased Rx ring to 256 descriptors from 128. o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary. o Remove alignment restrictions on Tx/Rx buffers. o Rewritten jumbo frame support code. o Add support for hardware assistend VLAN tag insertion/stripping. o Add support for Tx/Rx flow control based on patches from Peer Chen. [2] o Add a routine that detects whether ethernet address swap routines is required. [3] o Add a workaround that take MAC/PHY out of power down mode. o Add suspend/resume support. o style(9) and code clean up. Special thanks to Shigeaki Tagashira, the original porter of nfe(4), who submitted lots of patches, performed uncountable number of regression tests and maintained nfe(4) for a long time. Without his enthusiastic help and support I could never have completed this overhauling task. The only weak point of nfe(4) compared to nve(4) is instability of manual half-duplex media selection on certain hardwares(auto sensing media type should work for all cases, though). This was a long standing bug of nfe(4) and I still have no idea why it doesn't work on some hardwares.

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.
