frame, not the first. It is probably also not safe to free the mbuf chain as soon as the OWN bit is cleared on the first descriptor since the chip may not be done copying the frame into the transmit FIFO. Revert the part of of busdma conversion (if_dc.c rev 1.115) which changed dc_txeof() to look for the status in the first descriptor and free the mbuf chain when processing the first descriptor for the frame, and revert the matching changes elsewhere in the driver. This part of the busdma change caused the driver to report spurious collisions and output errors, even when running in full-duplex mode. Reverting the mbuf chain handling slightly complicates dc_dma_map_txbuf(), since it is responsible for setting the OWN bits on the descriptors, but does not normally have direct access to the mbuf chain.

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 ``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.
