Although that DPMS code did what the XFree86/Xorg sunffb(4x) does,

Tx interrupt moderation mechanism(delayed interrupts) or chipset bug.
If Tx interrupt moderation mechanism is the cause of false watchdog

WB (write-back) on x86 via control bits in PTEs and PDEs (including making
use of the PAT MSR). Changes include:
- A new pmap_mapdev_attr() function for amd64 and i386 which takes an
additional parameter (relative to pmap_mapdev()) specifying the cache
mode for this mapping. Note that on amd64 only WB mappings are done with
the direct map, all other modes result in a private mapping.
- pmap_mapdev() on i386 and amd64 now defaults to using UC (uncached)
mappings rather than WB. Previously we relied on the BIOS setting up
MTRR's to enforce memio regions being treated as UC. This might make
hw.cbb_start_memory unnecessary in some cases now for example.
- A new pmap_mapbios()/pmap_unmapbios() API has been added to allow places
that used pmap_mapdev() to map non-device memory (such as ACPI tables)
to do so using WB as before.

- Change the workaround for the autopad/checksum offload bug so that

This approach also gives us a chance to zero the pad space to avoid
possibly leaking data.
- With the PCIe devices, it looks issuing a TX command while there's
already a transmission in progress doesn't have any effect. In other
words, if you send two packets in rapid succession, the second one may
end up sitting in the TX DMA ring until another transmit command is
issued later in the future. Basically, if re_txeof() sees that there
are still descriptors outstanding, it needs to manually resume the
TX DMA channel by issuing another TX command to make sure all
transmissions are flushed out. (The PCI devices seem to keep the
TX channel moving until all descriptors have been consumed. I'm not
sure why the PCIe devices behave differently.)
(You can see this issue if you do the following test: plug an re(4)
interface into another host via crossover cable, and from the other
host do 'ping -c 2 <host with re(4) NIC>' to prime the ARP cache,
then do 'ping -c 1 -s 1473 <host with re(4) NIC>'. You're supposed
to see two packets sent in response, but you may only see one. If
you do 'ping -c 1 -s 1473 <host with re(4) NIC>' again, you'll
see two packets, but one will be the missing fragment from the last
ping, followed by one of the fragments from this ping.)
- Add the PCI ID for the US Robotics 997902 NIC, which is based on
the RTL8169S.
- Add a tsleep() of 1 second in re_detach() after the interrupt handler
is disconnected. This should allow any tasks queued up by the ISR
to drain. Now, I know you're supposed to use taskqueue_drain() for
this, but something about the way taskqueue_drain() works with
taskqueue_fast queues doesn't seem quite right, and I refuse to be
tricked into fixing it.
- Correct the PCI ID for the 8169SC/8110SC in the device list (I added
the macro for it to if_rlreg.h before, but forgot to use it.)
- Remove the extra interrupt spinlock I added previously. After giving it
some more thought, it's not really needed.
- Work around a hardware bug in some versions of the 8169. When sending
very small IP datagrams with checksum offload enabled, a conflict can
occur between the TX autopadding feature and the hardware checksumming
that can corrupt the outbound packet. This is the reason that checksum
offload sometimes breaks NFS: if you're using NFS over UDP, and you're
very unlucky, you might find yourself doing a fragmented NFS write where
the last fragment is smaller than the minimum ethernet frame size (60
bytes). (It's rare, but if you keep NFS running long enough it'll
happen.) If checksum offload is enabled, the chip will have to both
autopad the fragment and calculate its checksum header. This confuses
some revs of the 8169, causing the packet that appears on the wire
to be corrupted. (The IP addresses and the checksum field are mangled.)
This will cause the NFS write to fail. Unfortunately, when NFS retries,
it sends the same write request over and over again, and it keeps
failing, so NFS stays wedged.
(A simple way to provoke the failure is to connect the failing system
to a network with a known good machine and do "ping -s 1473 <badhost>"
from the good system. The ping will fail.)
Someone had previously worked around this using the heavy-handed
approahch of just disabling checksum offload. The correct fix is to
manually pad short frames where the TCP/IP stack has requested
checksum offloading. This allows us to have checksum offload turned
on by default but still let NFS work right.
- Not a bug, but change the ID strings for devices with hardware rev

mac-io bus, we cannot setup FAST interrupt handlers. This because we
use spinlocks to protect the hardware and all interrupt resources are
assigned the same interrupt handler. When the interrupt handler is

corresponding a single instance of this driver). This is a deadlock.

loading for the QLogic cards.
Because isp(4) exists before the root is mounted, it's not really
possible for us to use the kernel's linker to load modules directly
from disk- that's really too bad.
However, the this is still a net win in in that the firmware has
been split up on a per chip (and in some cases, functionality)
basis, so the amount of stuff loaded *can* be substantially less
than the 1.5MB of firmware images that ispfw now manages. That is,
each specific f/w set is now also built as a module. For example,
QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080
firmware is built as isp_1080_it.ko.
For compatibility purposes (i.e., to perturb folks the least), we
also still build all of the firmware as one ispfw.ko module.
This allows us to let 'ispfw_LOAD' keep on working in existing
loader.conf files. If you now want to strip this down to just
the firmware for your h/w, you can then change loader.conf to
load the f/w you specifically want.
We also still allow for ispfw to be statically built (e.g., for
PAE and sparc64).
Future changes will look at f/w unloading and also role switching
that then uses the kernel linker to load different ips f/w sets.

tree... John Baldwin noted that sio might pass values between probe
and attach via softc. It appears that sio does leave the hardware in
a known state after probing, so other drivers that try to probe might
leave it in a worse state. It doesn't seem to pass any data in softc,
however, that I could find... I think we should not be probing for
anything but nonPnP isa, but that's a change for another day.

cards: the chips are all marked "RTL8111B", but they put stickers on the
back that say "RTL8168B/8111B". The manual says there's only one HWREV code
for both the 8111B and 8168B devices, which is 0x30000000, but the cards
they sent me actually report HWREV of 0x38000000. Deciding to trust the
hardware in front of me rather than a possibly incorrect manual (it wouldn't
be the first time the HWREVs were incorrectly documented), I changed the
8168 revision code. It turns out this was a mistake though: 0x30000000
really is a valid for the 8168.
There are two possible reasons for there to be two different HWREVs:
1) 0x30000000 is used only for the 8168B and 0x38000000 is only for
the 8111B.
2) There were 8111/8168 rev A devices which both used code 0x30000000,
and the 8111B/8168B both use 0x38000000.
The product list on the RealTek website doesn't mention the existence of
any 8168/8111 rev A chips being in production though, and I've never seen
one, so until I get clarification from RealTek, I'm going to assume that
0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only.
So, the HWREV code for the 8168 has been put back to 0x30000000,
a new 8111 HWREV code has been added, and there are now separate
entries for recognizing both devices in the device list. This will
allow all devices to work, though if it turns out I'm wrong I may
need to change the ID strings

Finally fix the EEPROM reading code so that we can access the EEPROMs on all
devices. In order to access the EEPROM, we must select 'EEPROM programming'
mode, and then set the EEPROM chip select bit. Previously, we were setting
both bits simultaneously, which doesn't work: they must be set in the
right sequence.
Always obtain the station address from the EEPROM, now that EEPROM
reading works correctly.
Make the TX interrupt moderation code based on the internal timer
optional and turned off by default.
Make the re_diag() routine conditional and off by default. When it is

that really needed it.
Modify interrupt handling to use a fast interrupt handler and fast
taskqeueue.
Correct the rgephy driver so that it only applies the DSP fixup for
PHY revs 0 and 1. Later chips are fixed and don't need the fixup.
Make the rgephy driver advertise both 1000_FD and 1000_HD bits in
autoneg mode. A couple of the devices don't autoneg correctly unless
configured this way.

Thanks to brueffer for showing my how to test with altq/pf.
- Update the firmware to the latest released firmware
(1.4.3), which corresponds to the firmware in the
latest shipping drivers from Myricom. This firmware
fixes several bugs in the firmware's PCI-e implementation,
and it also changes the driver/firmware interface:
o TSO was added, and changed the format of the transmit
descriptors.
o The firmware no longer counts transmits descriptors,
but frames. So the driver needs to keep a count
of the number of frames sent.
o The weird interrupt strategy changed to a normal receive
return ring. This ring is much bigger, and we may be
able to support DEVICE_POLLING.
o Myricom's header files changed the name of firmware
related #define's and enums (s/_MCP_/FW_).
- Stopped spamming the console with lots of printfs unless
mxge_verbose (or bootverbose) is set.
- Made additional information available via sysctl, including
the results of a PCI-e DMA benchmark run at device reset.
- Decreased the excessively long timeouts when sending commands
from 2 seconds to 20ms.

firmware_get() will not work while resuming. Note that we can't
simply drop the FIRMWARE_UNLOAD flag, because that will result in
a firmware image that can never be unloaded by the user since the
firmware subsystem will hold a linker reference to it (it's not
clear that firmware_put() without FIRMWARE_UNLOAD ever does quite
what you'd want).

SK-NET GENESIS document says reading SK_ISSR should stop generating
further interrupts(Since we drop a driver lock before invoking
ifp->if_input handler we should disable interrupts in ISR in order
to protect integrity of softc from subsequent interrupts). But it
seems that there is possibility of loosing interrupts between
reading SK_ISSR and determining which interrupts are reported.
To cope with the situation we continuously read SK_ISSR register
until there are no interrupts. However, it seems that the above
work around doesn't fix all cases. To protect watchdog handler
from triggering false alarm add a work around code which try to
reclaim pending Tx descriptors before resetting hardware. This
should fix occasional watchdog timeout errors seen on this driver.

taskqueued interrupt mode is going to be quite complex. Since
the polling mode is considered legacy feature for em(4) driver,
the decision is made to make polling and new interrupt handler
mutually exclusive, selected at compile time.
If kernel is compiled with DEVICE_POLLING, the fast taskqueued
interrupt handler code is disabled and the em_poll() and legacy
em_intr() functions are enabled. Otherwise, legacy functions
are disabled and only em_intr_fast() code is compiled.
