Increase the default bpf buffer size used by naive apps that don't do
BIOCSBLEN, from 8k to 32k. The former value of 8192 is too small to
hold a normal jumbo Ethernet frame (circa 9k), 16k is a little small
for Large-jumbo (~16k) frames supported by newer gigabit
Ethernet/10Gbe, so (somewhat arbitrarily) increase the default to 32k.
Increase the upper limit to which BIOSBLEN can raise bpf buffer-size
drastically, to 1 Mbyte. State-of-the-art for packet capture circa
1999 was around 256k; savvy NetBSD developers now use 1 Mbyte.
Note that libpcap has been updated to do binary-search on BIOCSBLEN
values up to 1 Mbyte.
Work is in progress to make both values sysctl'able. Source comments
note that consensus on tech-net is that we should find some heuristic
to set the boot-time default values dynamically, based on system memory.
12160 Firmware Version 10.04.41 (10:30 Mar 21, 2003)
2200 Firmware Version 2.02.06 (08:39 Jun 26, 2003)
2300 Firmware Version 3.02.15 (08:26 Jul 21, 2003)
Matt's done some testing with it, and I've also tested on a very basic
setup with a QLA 2310 and a tower of 4 FC drives.
Unfortunately, there doesn't seem to be any change log for the firmware.
size (via BIOCSBLEN). Obtained from FreeBSD 4.x; originally from
http://www.tcpdump.org's version of libpcap.
Taken verbatim from the FreeBSD 4.9 version, lint and all, other than
increasing the maximum size from 32Kibyte to an extremely generous
4Mibytes. We assume root will configure the in-kernel maximum value
sensibly on small-memory machines.
(struct in6pcb* versus struct inpcb*) in ipsec_getpolicybysock().
Add new macros (in lieu of an abstract data type) for a ``generic''
PCB_T (points to a struct inpcb* or struct in6pcb*) to ipsec_osdep.h.
Use those new macros in ipsec_getpolicybysock() and elsewhere.
As posted to tech-net for comment/feedback, late 2003.
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt

This bit will be set if the clock lost power (and may therefore
not have the correct time). If this bit is set, the stored time
does not advance. So, when setting the clock, if that bit is set,
we simply clear it. It might be nice in some applications to pass
the information up a few layers if the bit is set when we read the
register initially. For now, though, we ignore it.
if the disklabel is missing the cpg parameter. Also print a warning
if this is skipped because of a missing fsize, frag or cpg disklabel parameter
