them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.
Ports that don't need to do this no longer need to supply a
dummy function.
network interfaces. This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us. In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software. This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.
We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.
Note: hardware-assisted checksumming defaults to "off". It is
enabled with ifconfig(8). See the manual page for details.
Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.
when the system is "warm", i.e. interrupts are not blocked anymore.
This seems to be necessary on my PS/2 Model 70 keyboard - without this,
system ends up in endless loop calling the keyboard intr routine if a key
is pressed when polling. This _may_ be just specific to level-triggered
interrupts PS/2 MCA uses, though it's more likely it's just the way the
particular keyboard controller works.

BMSR are wired to 0, yet the PHY supports 10baseT. So, to get around
this, we test the ANAR 10baseT bits after a PHY reset. These bits are
set according to input pin 180. If we see the 10baseT ANAR bits set,
we fake them in the BMSR so that we can actually autonegotiate 10baseT.
and default every PHY to 5 seconds (what we used before). If we find
Gig-E media on a PHY, bump it to 10 seconds, since it can take 5
seconds just to negotiate a Gig-E link.
from the pc532 "ncr" driver.
This gets me up to 300 KB/s from /dev/rsd0a on my A310. I think
bus_space_{read,write}_multi_1 and copy{in,out} are the bottlenecks now.
Handle special case for IFF_PROMISC. If only IFF_PROMISC
flag is changed, do not call an_init() to avoid initiating
reassociation to another access point. It is really
helpful for tcpdump(8).
way of doing business- modulo some startup spasms and peculiarities
of the way kthreads are started (*after* configuration, weird) and
some strangeness with the freeze/thaw code, what now happens is
that any of Loop Down, LIP, Loop Reset or Port Datbase or Name
Server Database Changed ASYNC events cause the queues to freeze
for this channel. The arrival of a Loop UP is not relevant.
What *is* relevant is that the Port Datbase or Name Server Changed
async event indicate that it's okay to go and (re)evaluate the
state of the FC link and (re)probe local loop and fabric membership.
We have a kthread do this because it's *sooooo* much nicer to be
able to sleep while doing the 130-250 mailbox commands it'll take
to re-evaluate things.
When the state is well known again, we can unfreeze the channel
queues. Then, as commands start arriving, we simply can start them
or bounce them with XS_SELTIMEOUT (if the device in question has
gone away). Previously, we did lazy evaluation, which meant that
if a change occurred, we would wait until the very *next* command
to go rebuild stuff.
The reason this is not sensible is:
a) Even with sleeping, you can hang up your system because you might be
making some poor stat(2) call pay the price of re-evaluating the whole
fabric.
b) If we ever really want to get to dynamic attachment/detachment, we
should find out sooner, rather than later, where things get to.
Split off ispminphys_1020 from ispminphys- a 1020 has a 24 bit limit-
not anything newer.
Re-enable LIPs and Loop Resets as async events- this allows the outer
layer to set policy about them.
Roll platform major && minor. Remove bogus waitq (no longer used).
Remove callout entry in softc (no longer used). Define some shorthands
for channels. Clean up a variety of cruft left over from the
thorpej_scsipi changeover.
