mbuf allocation fails, and fix (i hope) a couple of style bugs.
I believe these printf() are extremely dangerous because now they can
occur on every incoming packet and are not rate limited. They were
meant to warn the sysadmin about lack of resources, but now they
can become a nice way to panic your system under load.
Other drivers (e.g. the fxp driver) have nothing like this.
There is a pending discussion on putting this kind of warnings
elsewhere, and I hope we can fix this soon.
underlying unaligned bcopy) on incoming packets that are already
available (albeit unaligned) in a buffer.
The performance improvement varies, depending on CPU and memory
speed, but can be quite large especially on slow CPUs. I have seen
over 50% increase on forwarding speed on the sis driver for the
486/133 (embedded systems), which does exactly the same thing.
The behaviour is controlled by a sysctl variable, hw.dc_quick which
defaults to 1. Set it to 0 to restore the old behaviour.
After running a few experiments (in userland, though) I am convinced
that doing the m_devget() is detrimental to performance in almost
all cases.
Even if your CPU has degraded performance with misaligned data,
the bcopy() in the driver has the same overhead due to misaligment
as the one that you save in the uiomove(), plus you do one extra
copy and pollute the cache.
But more often than not, you do not even have to touch the payload,
e.g. when you are forwarding packets, and even in the often-cited
case of NFS, you often end up passing a pointer to the payload to
the disk controller.
In any case, you can play with the sysctl variable to toggle between
the two behaviours, and see if it makes a difference.

device cloned, and assign all further devices to depend on it. This
allows us to call dev_depends() on it at module unload time to get rid
of /dev/snp* (in the devfs case, anyway). For this to work, we must
not destroy the device at close time. [Idea stolen from if_tun.]
The above has the following sideaffects: (a) The snp device used by
watch(8) will remain after watch(8) exits. This is probably how it
should have been all along, and how it was before devfs came along.
(b) Module unload doesn't panic if there are any /dev/snp* devices
which haven't been used (and thus previously destroyed). Thus, we can
reenable the unload functionality disabled in rev. 1.65.

off chip that was on one prototype board. However, this appears to be
a design that many chipsets are compatible with its PPEC register set
(eg the Omega 82c094). Through the kindness of the Red Hat developer
David Woodhouse, I now have this datasheet.
I may take the advise of one of the bsd-nomads (whose name
unfortunately escapes me at the moment) and split out all these 16-bit
I/O mapped PCI devices into a separate driver...
that it has one BAR that's mapped to 0x3e0 and is I/O only. It does
not conform to the Yenta spec, like other PCI PCMICA bridges do (eg
the TI 1031, which is mostly a 1131 w/o 32bit card support). It
appears that this chip may also need to not route PCI interrupts
as well.
This chip is used in the NEC Versa 2430CD (and it appears that
sometimes it works, while other times it doesn't) and others in the
2400 series. While the NEC website claims Cardbus support, I can't figure
out how that is possible.
