interrupt source.
- Only do an outb() to the PIC to clear a bit in imen if the bit is set.
- Add a NUM_ISA_IRQS macro to replace uglier
'sizeof(array) / sizeof(member)' expressions along with a CTASSERT() to
ensure that the macro is correct.
than using legacy_pcib_attach(). The MP Table drivers don't use the $PIR,
and the legacy_pcib_attach() function probes and parses the $PIR in
addition to adding the pci bus child device.
o New function ip_findroute() to reduce code duplication for the
route lookup cases. (luigi)
o Store ip_len in host byte order on the stack instead of using
it via indirection from the mbuf. This allows to defer the host
byte conversion to a later point and makes a quicker fallback to
normal ip_input() processing. (luigi)
o Check if route is dampned with RTF_REJECT flag and drop packet
already here when ARP is unable to resolve destination address.
An ICMP unreachable is sent to inform the sender.
o Check if interface output queue is full and drop packet already
here. No ICMP notification is sent because signalling source quench
is depreciated.
o Check if media_state is down (used for ethernet type interfaces)
and drop the packet already here. An ICMP unreachable is sent to
inform the sender.
o Do not account sent packets to the interface address counters. They
are only for packets with that 'ia' as source address.
o Update and clarify some comments.

o Extend the if_data structure with an ifi_link_state field and
provide the corresponding defines for the valid states.
o The mii_linkchg() callback updates the ifi_link_state field
and calls rt_ifmsg() to notify listeners on the routing socket
in addition to the kqueue KNOTE.
o If vlans are configured on a physical interface notify and update
all vlan pseudo devices as well with the vlan_link_state() callback.

This is in preparation for media state change notification to the
routing socket.

o Fix and improve comments and references,
o Add PFIL_HOOKS, UFS_ACL and UFS_DIRHASH,
o Switch from SCHED_4BSD to SCHED_ULE,
o Remove SCSI_DELAY (there's no SCSI support),
- change pf_get_pool() argument rule_number type from u_int32_t
to u_int8_t, fixes corruption of address pools with large
rulesets (mcbride@)
- prevent endless loops with route-to (dhartmei@)
- limit option length to 2 octets max (frantzen@)

Rename ip_claim_next_hop() to m_claim_next_hop(), give it an extra arg
(the type of tag to claim) and push it out of ip_var.h into mbuf.h
alongside all of the other macros that work ok mbuf's and tag's.
parameter).
Keep using it only in the i386 NOTES for now. It is fairly MI, but it
doesn't use bus-space and has a couple of i386 i/o instructions in pci
intitialization.
intent was to make sure that message structs allocated off of the stack were
4-byte aligned. However, the macros as defined did absolutely nothing.
And since I2O forces you to manually copy messages down to the hardware, there
really is no point of enforced alignment anyways.
rename the control device from rasr%d to asr%d. This starts us down the
path of divorcing ourselves from a very bogus design in the management
apps. Since the apps are open source now, they will likely be updated
and fixed before 5.3.
Adjust staticness and a variable name for the split of cy.c into cy.c and
cy_isa.c. Use the new header required for the split to avoid repeating
declarations in cy_pci.c.
Put @includes in a better spot. Fix many cases of 2 space indents and spaces
between a function name and the parens. Use KASSERT instead of a home-rolled
ASSERT. Remove some undeeded caddr casts.
- Define option FORCECONSPEED to force the serial console to
be CONSPEED. I've run into a lot of boards in which
the detect for prior speed doesn't work and ends up with
broken console since it is at the wrong speed.
- If a serial port is marked as a console, but console=vidconsole
and if the serial ports doesn't exist it will be probed and
attached at a 8250 chip. Then writes to that will freeze the
system.
- Add an option flags 0x400000 to mark this as a potential
comconsole in-case the one flaged with 0x10 does not exist
in the system.
This makes it easier to deploy on systems with one or two serial ports.

- Use the dh_inserted member of the dispatch header in the Windows
timer structure to indicate that the timer has been "inserted into
the timer queue" (i.e. armed via timeout()). Use this as the value
to return to the caller in KeCancelTimer(). Previously, I was using
callout_pending(), but you can't use that with timeout()/untimeout()
without creating a potential race condition.
- Make ntoskrnl_init_timer() just a wrapper around ntoskrnl_init_timer_ex()
(reduces some code duplication).
- Drop Giant when entering if_ndis.c:ndis_tick() and
subr_ntorkrnl.c:ntoskrnl_timercall(). At the moment, I'm forced to
use system callwheel via timeout()/untimeout() to handle timers rather
than the callout API (struct callout is too big to fit inside the
Windows struct KTIMER, so I'm kind of hosed). Unfortunately, all
the callouts in the callwhere are not marked as MPSAFE, so when
one of them fires, it implicitly acquires Giant before invoking the
callback routine (and releases it when it returns). I don't need to
hold Giant, but there's no way to stop the callout code from acquiring
it as long as I'm using timeout()/untimeout(), so for now we cheat
by just dropping Giant right away (and re-acquiring it right before
the routine returns so keep the callout code happy). At some point,
I will need to solve this better, but for now this should be a suitable
workaround.
- Remove second license, the first was not that different and should be
fine.
- Add nexus_attach(), and do not perform its task in nexus_probe() any
more.
- Remove nexus_write_ivar(), since it was quite pointless.
- Remove superfluous devinfo members.
- Clean up some comments, minor style issues and prototypes.
