controllers. ICH based controllers are treated as 82559. 82557, earlier revision of 82558 and 82559ER have no WOL capability. o WOL support requires help of a firmware so add check whether hardware is capable of handling magic frames by reading EEPROM. o Enable accepting WOL frames only when hardware is about to suspend or shutdown. Previously fxp(4) used to allow receipt of magic frame under normal operation mode which could cause hardware hang if magic frame is received by hardware. Datasheet clearly states driver should not allow WOL frames under normal operation mode. o Disable WOL frame reception in device attach so have fxp(4) immunize against system hang which can be triggered by magic packets when the hardware is not in fully initialized state. o Don't reset all hardware configuration data in fxp_stop() otherwise important configuration data is lost and this would reset WOL configuration to default state which in turn cause hardware hang on receipt of magic frames. To fix the issue, preserve hardware configuration data by issuing a selective reset. o Explicitly disable interrupts after issuing selective reset as reset may unmask interrupts.

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.
