This makes initarm() for them a bit simpler, and gives us smaller diffs

For now to this by calling hypervisor_enable_irq(), this could be rewritten

This fix suggested by Charles Hannum (mycroft at netbsd dot org).
I/O registers that are used in early start-up stage. This replaces the
special bootstrap-time-only bus_space_map function in smdk{2410,2800}_machdep.c.
This makes SMDK{2410,2800}'s initarm() a bit simpler, and gives us smaller diffs
to other evbarm platforms.
An another good thing for SMDK2800 is that now we have all built-in peripheral
registers mapped in 2 segments. We may expect less TLB miss on I/O access
(very slightly).
- introduce t_segqlen, the number of segments in segq/timeq.
the name is from freebsd.
- rather than maintaining a copy of sack blocks (rcv_sack_block[]),
build it directly from the segment list when needed.
to be alloctated multiple times:
- we're allocating region of size 1
- there are holes in the extent, but all of size larger than 1
- there are 2 contigous allocations at the end of the extent, the last one
being of size 1.
While there fix a DIAGNOSTIC check: to check that a region is inside the extent
we need to check start and end, not only start.

0. Fix it by returning the peer's block size.
XXX: This is the minimal fix. Probably the buffer size should be initialized
somewhere else, but probably this would need some more code changes.
Add the usec to the secs before subtracting the usec offset - otherwise
I suspect the value can do horribly wrong!
Change all T_SVR4_GETHRESTIME to return sec + nanoseconds (I've not sure
this is correct, but I doubt the 32bit emulation in a 64bit kernel should
act differently to a 32bit kernel!)
Untested - I don't even have a sparc compile setup at the moment.
- TSO support.
- fix some error handling.
- remove mysterious RTK_NTXSEGS and use more appropriate values
for bus_dmamap_create.
- if we need more than all of our tx descriptors in order to transmit a packet,
just drop it rather than retrying infinitely.
1) After setting an input or output channel to pause, watch for DCH (DMA
halted) to be set before resetting the registers. The manual says this is
required. This *may* fix random auich lockups.
2) Add auich_{trigger,intr,halt}_pipe(), which can operate on any of the
input and output channels. This reduces code duplication quite a bit.
While I'm at it, fill in the mic interrupt handling.
3) The mic in interrupt is MINT, not MIINT. (The latter is modem input.)
* Only futz with the done list in the soft interrupt handler. In the hard
interrupt handler, do nothing except mask WDH and queue the soft interrupt.
This simplifies a bunch of code, removes two O(n^2) queue manipulations,
and gets rid of some really sketchy stuff around the queue head access.
* Use the auto-masking code at the end of the interrupt handler for both WDH
and RHSC interrupts. Again, this reduces the code a little, and avoids
multiple writebacks to the chip registers.
in connected state. Avoid a panic when the interface is configured
before being in connected state (e.g. when configured automatically by xend
when a domain is created).
Remove the padding bits from blkif_extent_t, so that the message size doesn't
change. You'll need xentools20-2.0.3nb1 if you upgrade your kernel
(the old tools didn't zero out the padding bits, and a new kernel will
interpret them as part of the device number).
previously-allocated pages may not have been loaned to the remote domain
yet. Let the called deal with this.
- clean up the TX and RX loops to use less MASK_NETIF_xX_IDX() calls
- When we're done with the queued TX requests, try again in case some new
ones are available
- avoid leaking a xmit page if we queued NB_XMIT_PAGES_BATCH requests.
- remove dead code.
Protect the callback queue with splvm()
XXX some debug printf about the callback stuff is left here. This is because
I've not been able to trigger this condition yet, so I've left them
until we sure the code works as intended.
- Use the correct IP header length variable for other-than-first packets.
- Remove redundant setting of the original IP header length in the first
packet's csum_data. (It's already set before ip_fragment() is called
in 1.147.)
to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz
supplied to bus_dmamap_create). dm_maxsegsz is reset to the value supplied to
bus_dmamap_create when the dmamap is unloaded.
Use "__uint64_t" etc. instead of pulling in "sys/socket.h" to avoid
namespace pollution. Based on comments made by Klaus Klein on the

kern.file, namely a 32/64 bit clean sysctl interface to the same data.
It also borrows a few things from struct vnode (if applicable) and
from struct proc, just to tie things together a bit more.
You can walk this list "by file" or "by pid". The former method is
similar to kern.file but omits the filehead, and the latter can give
you duplicates if multiple processes have the same struct file open,
but tells you which process it is.
This is just a quick fix to make KSTACK_DEBUG kernels compilable.
Formatting needs improvment (group lwps from one process together, etc).

field of the IP header (ip->ip-len) indicates they should be. This handles
the case where an ethernet frame has been padded to meet the minimum ethernet
frame length or erroneously (my cisco switch unnecessarily adds 4 bytes to its
SYN). This padding will be included in the hardware checksum and may be
non-zero, thus making it incorrect.
Also, clear csum_flags when we want a s/w checksum, since we may have started
down the h/w checksum path and determined that it was not usable.
While here, clean-up a few WS nits and ifdef INET the hardware checksum code.

Use log(9) to warn the user instead of printf(9). Since the theory is that
the Ifile is "always in cache", but the greater performance risk is
when the inode entries can't be held in cache, note these two cases
separately, at different log levels (notice and warning, respectively).

This fixes a race condition that could cause "panic: tcp_output REXMT". See

(1) in pmap_enter_pv(), we would always mark the header entry wired, even if
the new entry wasn't put there. noticed by Juergen Hannken-Illjes.
(2) in pmap_unwire(), we would never examine the header entry.

while I'm here, move the counter increment in the pmap_enter() path to be
next to the corresponding PV_WIRE() call so it's more obvious they match.
Fix the work-around for the NIC bug where it skips to rx

with aif_get_mailbox(). Make it return uint32_t instead of 'int'.
* Add an AAC_GET_MAILBOX() macro and change AAC_GET_MAILBOXSTATUS() to use
that.
* Update the Dell PERC 2QC quirk code to use AAC_GET_MAILBOX instead of the
StrongARM-specific code. While StrongARM access is correct for that card,
it's a bad example of how to access the mailbox registers.
* Add the GETINFO command and use it to get and display the card's
supported options at a verbose level during attachment.
The value of 50 dates back to 4.3BSD and 10Mbit interfaces.
Gigabit interfaces are 100x faster, and by observation, when heavy
interrupt mitigation is enabled, gigabit interfaces can enqueue 40 packets
or more in a single hardware interrupt. So IFQ_MAXLEN of 256 is adequate
for at least four gigabit interfaces.
Increasing IFQ_MAXLEN discussed and approved, in priniciple, circa Apr 2004.
The value is sysctl'able, so the default is no longer so critical,
but (imho) best to tune for high-performane systems by default.

I have no clue if this is correct, but it matches the style in

Fixes in that patch for pre-existing TCP pcb initializations were already
committed to NetBSD-current, so are not included in this commit.
The SACK patch has been observed to correctly negotiate and respond,
to SACKs in wide-area traffic.
There are two indepenently-observed, as-yet-unresolved anomalies:
First, seeing unexplained delays between in fast retransmission
(potentially explainable by an 0.2sec RTT between adjacent
ethernet/wifi NICs); and second, peculiar and unepxlained TCP
retransmits observed over an ath0 card.
After discussion with several interested developers, I'm committing
this now, as-is, for more eyes to use and look over. Current hypothesis
is that the anomalies above may in fact be due to link/level (hardware,
driver, HAL, firmware) abberations in the test setup, affecting both
Kentaro's wired-Ethernet NIC and in my two (different) WiFi NICs.

o Don't stop interface on USB tx errs, just drop packet
o use IFQ_IS_EMPTY rather than check if_snd for NULL head

Fortunately, lower bytes of PA and VA for intio devices were identical
on -current pmap, but the problem appears on new yamt-km which has differnt
