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.
with net byte order. Change byte order to net in ng_ipfw_input(), change
byte order to host before ip_output(), do not change before ip_input().

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.

Instead, use the chip_type of DL100XX instead. This is more inline
with how the AX88190 support was added, and seems a little cleaner.

check to prevent overflow of the addressable threshold.
This fixes some reports of rl(4) slowness, believed to be related to ALTQ
before.

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.
pessmize the error recover path through edintr by calling these

does a lot in it, so an extra function call will be lost in the noise.
It also happens rarely.

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.
Older cards have it reversed.
Also, use some already defined values instead of magic numbers.

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.

using older firmware.
