Note that if_aue doesn't strictly depend on usb because it uses the
method interface for calls rather than using internal symbols, and
because it's a child driver of usb and therefore will not try and do
anything unless the parent usb code is loaded at some point. if_aue does
strictly depend on miibus as it will fail to link if it is missing.
bus/driver/kobj system. I am not 100% sure that this is the correct fix,
but it is harmless and does seem to solve the problem. At worst, it could
cause a tiny memory leak at unload time - this is better than a free(NULL)
and subsequent panic. I'm waiting for comments from Doug about this.
This may yet be backed out and fixed differently.
The change itself is to increment the reference count on drivers in one
case where it appears to have been missed. When everything is unloaded,
kobj_class_free() was being called twice in some cases, and panicing the
second time.
version dependency system. This isn't quite finished, but it is at a
useful stage to do a functional checkpoint.
Highlights:
- version and dependency metadata is gathered via linker sets, so things
are handled the same for static kernels and code built to live in a kld.
- The dependencies are at module level (versus at file level).
- Dependencies determine kld symbol search order - this means that you
cannot link against symbols in another file unless you depend on it. This
is so that you cannot accidently unload the target out from underneath
the ones referencing it.
- It is flexible enough that we can put tags in #include files and macros
so that we can get decent hooks for enforcing recompiles on incompatable
ABI changes. eg: if we change struct proc, we could force a recompile
for all kld's that reference the proc struct.
- Tangled dependency references at boot time are sorted. Files are
relocated once all their dependencies are already relocated.
Caveats:
- Loader support is incomplete, but has been worked on seperately.
- Actual enforcement of the version number tags is not active yet - just
the module dependencies are live. The actual structure of versioning
hasn't been agreed on yet. (eg: major.minor, or whatever)
- There is some backwards compatability for old modules without metadata
but I'm not sure how good it is.
This is based on work originally done by Boris Popov (bp@freebsd.org),
but I'm not sure he'd recognize much of it now. Don't blame him. :-)
Also, ideas have been borrowed from Mike Smith.
53C810 non 'A', 53C815 and 53C825 non 'A' are now
attached by the driver (by default).
The driver uses a different SCRIPTS set based on
MEMORY MOVE instructions for these chips.
2 SCRIPTS sets (firmwares) numbered #1 and #2 are
used for the whole support of the 53C8XX family
to get possible:
- FW #1 : Only based on MEMORY MOVE instructions.
Selected for 810, 815, 825.
- FW #2 : LOAD/STORE based. This is the firmware
also used by previous driver versions.
Selected for other chips.
When both `ncr' and `sym' are configured, `sym'
will now attach all the 53C8XX devices by default.
Previous balancing between `ncr' and `sym' can be
preserved by:
- Either editing sym_conf.h and commenting the
following compile option:
#define SYM_CONF_GENERIC_SUPPORT
(This also saves about 3.5Kb of kernel memory).
- Or setting kernel config option
SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40)
to PPTP) with more generic PacketAliasRedirectProto().
Major number is not bumped because it is believed that noone
has started using PacketAliasRedirectPptp() yet.
reset their grace timer as their ownership crossed the soft limit
threshhold. Thus if they had been over their limit in the past,
they were suddenly penalized as if they had been over their limit
ever since. The fix is to check when root gives away files, that
when the receiving user crosses their soft limit, their grace timer
is reset. See the PR report for a detailed method of reproducing
the bug.

first. This will fix a few cards that hang on the WD probe. He tells
me that PAO went one step farther and removed the WD proble completely
and none of the cards in the 2.x database broke in PAO3. Since I'm
more conservative in this code, I'm just swapping the order, which he
said also fixed his problem.

program running under linux emulation, the script binary is checked for
in /compat/linux first. Without this patch the wrong script binary
(i.e. the FreeBSD binary) will be run instead of the linux binary.
For example, #!/bin/sh, thus breaking out of linux compatibility mode.
This solves a number of problems people have had installing linux
software on FreeBSD boxes.
This driver should support both the SSI (V.35 etc) E1/T1 unchannelized,

- Include telling drivers ethernet address if Network node ID
tuple is available. This is usefull for some bogus ehter cards which
can't get correct ethernet address from CIS tupple.
