7bd12fe3ee Two problems here:
1.  Dependency on netgraph module was broken (wrong version).
2.  Netgraph node type was never destroyed on unload.  This
    was masked by problem #1.

Fixed both by using NETGRAPH_INIT().  Now netgraph node type
is created on module load, as in the rest of netgraph modules.

1a98d94fcf Bumped up the driver version, following recent changes. 2005-02-12 01:16:28 +00:00

ef40a850a7 Really old PCMCIA cards stored the MAC address in the attribute memory
at some offset.  Unlike newer cards, the MAC address wasn't part of
the CIS as a specific FUNCE.  These older cards were having their MAC
address show up as 0:2:4:6:8:a because that's what's in the ROM
locations that would be there in a real ne2000.

This patch allows one to specify the offset for the MAC address for
these cards.  Specify one for the IBM Ethernet II card, as it is one
that has this problem.  One shouldn't specify this unless the MAC
address really isn't in the CIS at all.

Side note: The novell probe likely shouldn't read the MAC address, and
that should be moved to the bus specific attach routine(s), maybe as a
convenience function in if_ed_novell.c.

My IBM Ethernet II (aka Info Mover) now has a believable MAC address.

b9befdc94b Add a bit more caveat text about MUTEX_PROFILING -- try to avoid using it
with other profiling and debugging options, such as INVARIANTS, WITNESS,
kernel profiling, etc.  They all interfere with each other nastily and
will generate fairly useless results.

eeb5ed79cb Add SIGTHR (32) into list of signals permitted to be delivered to the
suid application. The problem is that Linux applications using old Linux
threads (pre-NPTL) use signal 32 (linux SIGRTMIN) for communication between
thread-processes. If such an linux application is installed suid or sgid
and security.bsd.conservative_signals=1 (default), then permission will be
denied to send such a signal and the application will freeze.

I believe the same will be true for native applications that use libthr,
since libthr uses SIGTHR for implementing conditional variables.

1989b5df64 Eliminate the ED_VENDOR_{PCCARD,LINKSYS} types. These cards really
are NOVELL NE2000 with just a tiny quirk that's non vendor specific.
Instead, use the chip_type of DL100XX instead.  This is more inline
with how the AX88190 support was added, and seems a little cleaner.

e8769beaa3 Adjust TX threshold on every TX underrun. Some supported cards (8139-based)
can retransmit on TX underrun and set TOK in addition to TUND.  Also add a
check to prevent overflow of the addressable threshold.

This fixes some reports of rl(4) slowness, believed to be related to ALTQ
before.

6df119b425 When processing a timeout() callout and returning it to the free
list, set `curr_callout' to NULL. This ensures that we won't attempt
to cancel the current callout if the original callout structure
gets recycled while we wait to acquire Giant.

This is reported to fix an intermittent syscons problem that was
introduced by revision 1.96.

6ffaa0a101 Move enable/disable 16bit access routines into if_ed. Slightly
pessmize the error recover path through edintr by calling these
functions, rather than expanding it inline.  This error path already
does a lot in it, so an extra function call will be lost in the noise.
It also happens rarely.

c4f26f55ee Implement support for buffers larger than PAGE_SIZE in MemGuard. Adds
a little bit of complexity but performance requirements lacking (this is
a debugging allocator after all), it's really not too bad (still
only 317 lines).

Also add an additional check to help catch really weird 3-threads-involved
races: make memguard_free() write to the first page handed back, always,
before it does anything else.

Note that there is still a problem in VM+PMAP (specifically with
vm_map_protect) w.r.t. MemGuard uses it, but this will be fixed shortly
and this change stands on its own.

885ba93847 Optimize the way reference counting is performed with Mbufs. We
do not need to perform an extra memory fetch in the Packet (Mbuf+Cluster)
constructor to initialize the reference counter anymore.  The reference
counts are located in a separate memory region (in the slab header,
because this zone is UMA_ZONE_REFCNT), so the memory fetch resulted very
often in a cache miss.  Additionally, and perhaps more significantly,
optimize the free mbuf+cluster (packet) case, which is very common, to
no longer require an atomic operation on free (to verify the reference
counter) if the reference on the cluster has never been increased (also
very common).  Reduces an atomic on mbuf free on average.
