properly. This causes the autonegotiation to e.g. never establish a 100baseTX full-duplex link. The solution to this problem is to manually write the capabilities from the BMSR to the ANAR every time a media change occurs, even when already in autonegotiation mode. The NetBSD way of doing this is to set their MIIF_FORCEANEG flag in the NIC driver. This causes mii_phy_setmedia() to call mii_phy_auto() (which will set the ANAR according to the BMSR) even when the PHY alread is in autonegotiation mode. However, while doing the same on FreeBSD (which involves porting the MIIF_FORCEANEG flag and converting nsphy.c to use mii_phy_setmedia()) fixes autonegotiation, using mii_phy_setmedia() causes this driver to no longer work properly in the other modes. Another drawback of that approach is that this will also force writing the ANAR on other PHYs whose drivers use mii_phy_setmedia() and which are used with a NIC whose driver sets MIIF_FORCEANEG (e.g. hme(4) is known to be used together with 3 different PHYs while only the DP83840A require this workaround). So instead of moving to MIIF_FORCEANEG, just call mii_phy_auto() in nsphy_service() unconditionally when hanging off of a hme(4) and serving a media change This is part 1/2 of fixing autonegotiation on hme(4) using DP83840A PHYs. |

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.
