'options MAC') as long as IO_NOMACCHECK is not set in the IO flags.
If IO_NOMACCHECK is set, bypass MAC checks in vn_rdwr(). This allows
vn_rdwr() to be used as a utility function inside of file systems
where MAC checks have already been performed, or where the operation
is being done on behalf of the kernel not the user.

enabled and the kernel provides the MAC registration and entry point
service. Declare a dependency on that module service for any
MAC module registered using mac_policy.h. For now, hard code the
version as 1, but once we've come up with a versioning policy, we'll
move to a #define of some sort. In the mean time, this will prevent
loading a MAC module when 'options MAC' isn't present, which (due to
a bug in the kernel linker) can result if the MAC module is preloaded
via loader.conf.

indicate that the calling code has already performed necessary MAC
checks (if any) for this operation. This flag will help resolve
layering problems that existing because vn_rdwr() is called both
on behalf of user processes directly (such as in system calls of
various sorts, during core dumps, etc), as well as deep in the file
system code on behalf of the file system (such as in UFS, ext2fs,
etc). Code that is acting on behalf of a kernel service rather
than explicitly on behalf of a user process will specify this flag.
By default, MAC checks will be performed (and generally should
be performed).

access control: as with SVR4, very few changes required since almost
all services are implemented by wrapping existing native FreeBSD
system calls. Only readdir() calls need additional instrumentation.

SVR4 emulation relating to readdir() and fd_revoke(). All other
services appear to be implemented by simply wrapping existing
FreeBSD native system call implementations, so don't require local
instrumentation in the emulator module.

This is an architecture that present a thing message passing interface
to the OS. You can query as to how many ports and what kind are attached
and enable them and so on.
A less grand view is that this is just another way to package SCSI (SPI or
FC) and FC-IP into a one-driver interface set.
This driver support the following hardware:
LSI FC909: Single channel, 1Gbps, Fibre Channel (FC-SCSI only)
LSI FC929: Dual Channel, 1-2Gbps, Fibre Channel (FC-SCSI only)
LSI 53c1020: Single Channel, Ultra4 (320M) (Untested)
LSI 53c1030: Dual Channel, Ultra4 (320M)
Currently it's in fair shape, but expect a lot of changes over the
next few weeks as it stabilizes.

The driver is mostly from some folks from Jeff Roberson's company- I've
been slowly migrating it to broader support that I it came to me as.
The hardware used in developing support came from:
FC909: LSI-Logic, Advansys (now Connetix)
FC929: LSI-Logic
53c1030: Antares Microsystems (they make a very fine board!)

(not a bug) of vn_rdwr(), so we turn it off by supplying aresid param.

you can start it in a small window, but it doesn't always display
anything sensible. Resizing the window does work though.
The patch is a slightly simpler one than Sheldon's in the PR.
