0e85f214e3 Add a new primitive, XPT_SCAN_TGT, to cover the range between scanning a
whole bus (XPT_SCAN_BUS) and a single lun on that bus (XPT_SCAN_LUN).

It's less resource comsumptive than scanning a whole bus when the
caller knows only one target has changes.

f25a8a0150 Add uep(4), driver for USB onscreen touch panel from eGalax.
The driver is stub. It just creates device entry and feeds
reassembled packets from hardware into it.

If in future we would port wsmouse(4) from NetBSD, or make
sysmouse(4) to support absolute motion events, then the driver
can be extended to act as system mouse. Meanwhile, it just
presents a /dev/uep0, that can be utilized by X driver, that
I am going to commit to ports tree soon.

The name for the driver is chosen to be the same as in NetBSD,
however, due to different USB stacks this driver isn't a port.

79bf3fcd18 On PowerMac11,2 and (presumably) PowerMac12,1, we need to quiesce the
firmware in order to take over control of the SMU. Without doing this,
the firmware background process doing fan control will run amok as we
take over the system and crash the management chip.

This is limited to these two machines because our kernel is heavily
dependent on firmware accesses, and so quiescing firmware can cause
nasty problems.

f7a5f7371a If controller received bad frames make sure to update newly added
RFA. Also drop frames that have either CRC error or alignment
error. Normally bad frames are not received at all. But controllers
running in promiscuous mode will receive bad frames. 82557 will
also receive bad frames to receive VLAN oversized frames.

While I'm here mark RNR condition if driver happen to see RNR in
RFA status and restart RU to receive frames again. Because driver
checks all received frames in RX loop, RNR condition could be set
in the middle of RX processing. Just relying on RNR interrupt was
not enough.

This change fixes "Memory modified after free" issue when fxp(4)

Thanks to Masa Murayama who confirmed SiS190 also has the same

fragmentation of mbuf chain to 32 from 16 because TSO can send 64KB
sized packet which in turn requires long list of mbuf chain. Due to
lack of documentation, I'm not sure whether driver have to pull up
ethernet/IP/TCP header with options to make controller work but
driver have to parse TCP header to update pseudo TCP checksum
anyway. The controller expects pseudo TCP checksum computed by
upper stack and the checksum should follow the MS NDIS
specification to make TSO work.

8da9c50775 Export hardware MAC statistics through sysctl node. Previously
fxp(4) already used to extract most hardware MAC statistics but it
didn't show them. With this change, all MAC statistics counters
are exported. Because there are a couple of new counters for 82558
and 82559, enable extended MAC statistics functionality to get
these counters. Accoring to public data sheet, 82559 MAC statistics
return 24 DWORD counters(3 counters are unknown at this moment) so
increase MAC counter structure to meet the MAC statistics block size.
The completion of MAC counter dump is now checked against
FXP_STATS_DR_COMPLETE status code which is appended at the end of
status block. Previously fxp(4) ignored the status of the
FXP_SCB_COMMAND_CU_DUMPRESET command. fxp(4) does not wait for the
completion of pending command before issuing
FXP_SCB_COMMAND_CU_DUMPRESET. Instead it skips the command and try
it next time. This scheme may show better performance but there is
chance to loose updated counters after stopping controller. So make
sure to update MAC statistics in fxp_stop().
While I'm here move sysctl node creation to fxp_sysctl_node().

7251782989 8255x configure command requires number of bytes of configuration
table. The default size of the configuration table was 22 bytes. To
use extended feature of 82550/82551 the configuration table size
was expanded to 32 bytes. The added configuration for 82550/82551
specifies VLAN hardware tagging and IPSec configuration as well as
TCO.
To make configuration easier fxp(4) used a configuration template
and the template was copied to configuration table. After that,
some parameters of the configuration table was changed depending on
controller type and operation mode. However the size of template
was 22 bytes so some configuration parameters were not properly
initialized on 82550/82551.
Fix this by increasing the template size. For 82557, 82558 and
82559 the size of the configuration is still 22 bytes.

55c978ba9d Enable multi-descriptor transmisstion for fragmented mbufs. There
is no more need to defragment mbufs. After transmitting the
multi-fragmented frame, the controller updates only the first
descriptor of multi-descriptor transmission so it's driver's
responsibility to clear OWN bits of remaining descriptor of
multi-descriptor transmission. It seems the controller behaves much
like jme(4) controllers in descriptor handling.

31fefd0d5d Make sure to check whether driver is running before processing
received frames. Also check driver has valid ifp pointer before
calling msk_stop() in device_shutdown handler. While I'm here
remove unnecessary accesses to interrupt mask registers in
device_shutdown handler because driver puts the controller into
reset state.
With these changes, msk(4) now survive from heavy RX traffic(1byte
UDP frame) while reboot is in progress.

c909aebcbb - Remove more dead code[1]. Since r207330, we only need to check division
by zero of the second argument 'from'.
- Prefer u_int32_t over unsigned int to make its intention more clearer.
- Move the function to a header file and make it a static inline function.

917825acb9 - Don't set CAS_PCS_DATAPATH to anything except CAS_PCS_DATAPATH_SERDES
on Cassini using the external PCS SERDES otherwise unaligned access
  traps and other strange effects happen with some machines. Don't touch
  the MIF which is unused in that case either. These changes require the
  PHY type to use to be determined via the OFW device tree or from the
  VPD in machines without the former.
- Disable the SERDES pins of Saturn when not used in order to save power
  and ensure they are enabled otherwise.
- In cas_attach() use the correct register offset for CAS_PCS_CONF_EN.
- Add some bus space barriers missing in the PCS code path.

These changes make the Sun GigaSwift Ethernet 1.0 MMF cards as well as
the on-board interfaces found in Sun Fire B100s Blade Server work.

5fdd0a335f Acquire the page lock around vm_page_unwire(). For consistency, extend the
scope of the object lock in agp_i810.c.  (In this specific case, the scope
of the object lock shouldn't matter, but I don't want to create a bad
example that might be copied to a case where it did matter.)

e50d35e6c6 Add new tunable 'net.link.ifqmaxlen' to set default send interface
queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.
