turns out that there's something of a hole in our new fabric name server stuff. We ask the name server for entities that have registered as a specific type. That type is FC-SCSI. If the entity hasn't performed a REGISTER FC4 TYPES, the fabric nameserver won't return it. This brings this driver to a bit of a fork in the road as to what the right thing to do is. For servicing the needs of accessing FC-SCSI devices, this method is fine, and to be preferred. It is extremely unlikely we're interested in fabric devices that *don't* register correctly. If I ever get around to adding an FC-IP stack, then asking for devices that have registers as FC-IP types is also the right thing to do. So- asking the fabric nameserver for a specific type is fine, *as long as you are only interested in specific types*. If, on the other hand, you want to create (as for management tool support) a picture of everything on the fabric, this is *not* so fine. There are a large class of FC-SCSI *initiators* who *don't* correctly register, so we never will *see* them. Is this a problem? Yes, but only a little one. If we want to do such management tool support, we should probably run a *different* fabric nameserver query algorithm. Better yet, we should talk to the management nameserver in Brocade switches instead of the standard FC-GS-2 fabric nameserver (which can be unwieldy). Other changes: if we've overrrides marked, don't set some default values from reading NVRAM. This allows us to override things like EXEC throttle without having to ignore NVRAM entirely.

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/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.
