because we use RDTSC instruction to calculate difference in CPU ticks, which
is supposedly constant for the case. Now we support cpu_get_nominal_mhz()

because cpu_est_clockrate() is often times abused to find maximum frequency
of the processor.

This bug manifested itself after repeated device arrivals and
departures. The root of the problem was that the last entry in the
reply array wasn't initialized/allocated. So every time we got
around to that event, we had a bogus address.
There were a couple more problems with the code that are also fixed:
- The reply mechanism was being treated as sequential (indexed by
sc->replycurindex) even though the spec says that the driver
should use the ReplyFrameAddress field of the post queue
descriptor to figure out where the reply is. There is no
guarantee that the reply descriptors will be used in sequential
order.
- The second word of the reply post queue descriptor wasn't being
checked in mps_intr_locked() to make sure that it wasn't
0xffffffff. So the driver could potentially come across a
partially DMAed descriptor.
- The number of replies allocated was one less than the actual
size of the queue. Instead, it was the size of the number of
replies that can be used at one time. (Which is one less than
the size of the queue.)
mps.c: When initializing the entries in the reply free
queue, make sure we initialize the full number that
we tell the chip we have (sc->fqdepth), not the
number that can be used at any one time (sc->num_replies).
When allocating replies, make sure we allocate the
number of replies that we've told the chip exist,
not just the number that can be used simultaneously.
Use the ReplyFrameAddress field of the post queue
descriptor to figure out which reply is being
referenced. This is what the spec says to do, and
the spec doesn't guarantee that the replies will be
used in order.
Put a check in to verify that the reply address passed
back from the card is valid. (Panic if it isn't, we'll
panic when we try to deference the reply pointer in any
case.)
In mps_intr_locked(), verify that the second word of the
post queue descriptor is not 0xffffffff in addition to
verifying that the unused flag is not set, so we can
make sure we didn't get a partially DMAed descriptor.
Remove references to sc->replycurindex, it isn't needed
now.
mpsvar.h: Remove replycurindex from the softc, it isn't needed now.

AX88772 controllers. ASIX added a new feature for AX88178/AX88772
controllers which allows combining multiple TX frames into a single
big frame. This was to overcome one of USB limitation where it
can't generate more than 8k interrupts/sec which in turn means USB
ethernet controllers can not send more than 8k packets per second.
Using ASIX's feature greatly enhanced TX performance(more than 3~4
times) compared to 7.x driver. However it seems r184610 removed
boundary checking for buffered frames which in turn caused
instability issues under certain conditions. In addition, using
ASIX's feature triggered another issue which made USB controller
hang under certain conditions. Restarting ethernet controller
didn't help under this hang condition and unplugging and replugging
the controller was the only solution. I believe there is a silicon
bug in TX frame combining feature on AX88178/AX88772 controllers.
To address these issues, reintroduce the boundary checking for both
AX88178 and AX88772 after copying a frame to USB buffer and do not
use ASIX's multiple frame combining feature. Instead, use USB
controller's multi-frame transmit capability to enhance TX
performance as suggested by Hans[1].
This should fix a long standing axe(4) instability issues reported
on AX88772 and AX88178 controllers. While I'm here remove
unnecessary TX frame length check since upper stack always
guarantee the size of a frame to be less than MCLBYTES.

This includes support in the kernel, camcontrol(8), libcam and the mps(4)
driver for SMP passthrough.
The CAM SCSI probe code has been modified to fetch Inquiry VPD page 0x00
to determine supported pages, and will now fetch page 0x83 in addition to
page 0x80 if supported.
Add two new CAM CCBs, XPT_SMP_IO, and XPT_GDEV_ADVINFO. The SMP CCB is
intended for SMP requests and responses. The ADVINFO is currently used to
fetch cached VPD page 0x83 data from the transport layer, but is intended
to be extensible to fetch other types of device-specific data.
SMP-only devices are not currently represented in the CAM topology, and so
the current semantics are that the SIM will route SMP CCBs to either the
addressed device, if it contains an SMP target, or its parent, if it
contains an SMP target. (This is noted in cam_ccb.h, since it will change
later once we have the ability to have SMP-only devices in CAM's topology.)
smp_all.c,
smp_all.h: New helper routines for SMP. This includes
SMP request building routines, response parsing
routines, error decoding routines, and structure
definitions for a number of SMP commands.
libcam/Makefile: Add smp_all.c to libcam, so that SMP functionality
is available to userland applications.
camcontrol.8,
camcontrol.c: Add smp passthrough support to camcontrol. Several
new subcommands are now available:
'smpcmd' functions much like 'cmd', except that it
allows the user to send generic SMP commands.
'smprg' sends the SMP report general command, and
displays the decoded output. It will automatically
fetch extended output if it is available.
'smppc' sends the SMP phy control command, with any
number of potential options. Among other things,
this allows the user to reset a phy on a SAS
expander, or disable a phy on an expander.
'smpmaninfo' sends the SMP report manufacturer
information and displays the decoded output.
'smpphylist' displays a list of phys on an
expander, and the CAM devices attached to those
phys, if any.
cam.h,
cam.c: Add a status value for SMP errors
(CAM_SMP_STATUS_ERROR).
Add a missing description for CAM_SCSI_IT_NEXUS_LOST.
Add support for SMP commands to cam_error_string().
cam_ccb.h: Rename the CAM_DIR_RESV flag to CAM_DIR_BOTH. SMP

request and response.
Add a fill routine for SMP CCBs.
Add the XPT_GDEV_ADVINFO CCB. This is currently

transport later, but is extensible to fetch many
other types of data.

and XPT_GDEV_ADVINFO CCBs.
cam_xpt.c: Add support for executing XPT_SMP_IO CCBs.
cam_xpt_internal.h: Add fields for VPD pages 0x00 and 0x83 in struct

VPD page 0x83 data and pulls out a SAS address.
scsi_all.h: Add VPD page 0x00 and 0x83 structures, and a
prototype for scsi_get_sas_addr().
scsi_pass.c: Add support for mapping buffers in XPT_SMP_IO and
XPT_GDEV_ADVINFO CCBs.
scsi_xpt.c: In the SCSI probe code, first ask the device for
VPD page 0x00. If any VPD pages are supported,
that page is required to be implemented. Based on
the response, we may probe for the serial number
(page 0x80) or device id (page 0x83).
Add support for the XPT_GDEV_ADVINFO CCB.
sys/conf/files: Add smp_all.c.
mps.c: Add support for passing in a uio in mps_map_command(),
so we can map a S/G list at once.
Add support for SMP passthrough commands in
mps_data_cb(). SMP is a special case, because the
first buffer in the S/G list is outbound and the
second buffer is inbound.
Add support for warning the user if the busdma code
comes back with more buffers than will work for the
command. This will, for example, help the user
determine why an SMP command failed if busdma comes
back with three buffers.
mps_pci.c: Add sys/uio.h.
mps_sas.c: Add the SAS address and the parent handle to the
list of fields we pull from device page 0 and cache
in struct mpssas_target. These are needed for SMP
passthrough.
Add support for the XPT_SMP_IO CCB. For now, this
CCB is routed to the addressed device if it supports
SMP, or to its parent if it does not and the parent
does. This is necessary because CAM does not
currently support SMP-only nodes in the topology.
Make SMP passthrough support conditional on
__FreeBSD_version >= 900026. This will make it
easier to MFC this change to the driver without
MFCing the CAM changes as well.

mpsvar.h: Add a uio and iovecs into struct mps_command for
SMP passthrough commands.
Add a cm_max_segs field to struct mps_command so
that we can warn the user if busdma comes back with
too many segments.
Clear the cm_reply when a command gets freed. If

NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care

following advantages:
o allows flow control advertisement with autonegotiation to be

set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.

IFM_1000_T master mode support now is generally available with all PHY
drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's

controller does not perform automatic switching from 1000Mbps link
to 10/100Mbps link when WOL is activated. Implement establishing
10/100Mps link with auto-negotiation in driver. Link status change
handler was modified to remove taskqueue based approach since driver
now needs synchronous handling for link establishment.

and updated comments in the usb_quirk.h header file.
The main purpose of this is to expose the quirks for ejecting 3G
modules. usb_modeswitch in Linux does a great job of collecting
information on these, and with the quirks module people can try out the
modeswitch config file entries on FreeBSD, hence the SCSI strings in the
man page.

does-not-exist error when no client interface module is installed instead
of dereferencing NULL pointers. This eases implementation of platforms
that may or may not have Open Firmware.
It seems RTL8169/RTL8168/RTL810xE has a kind of interrupt
moderation mechanism but it is not documented at all. The magic
value dramatically reduced number of interrupts without noticeable
performance drops so apply it to all RTL8169/RTL8169 controllers.
Vendor's FreeBSD driver also applies it to RTL810xE controllers but
their Linux driver explicitly cleared the register, so do not
enable interrupt moderation for RTL810xE controllers.
While I'm here sort 8169 specific registers.

There were a couple of attempts in the past to reduce it since it
took more than 1ms. Because mii_tick() periodically polls link
status, waiting more than 1ms for each GMII register access was
overkill. Unfortunately all previous attempts were failed with
various ways on different controllers.
This time, add additional 20us dealy at the end of GMII register
access which seems to requirement of all RealTek controllers to
issue next GMII register access request. This is the same way what
Linux does.
controllers. sk(4) never reprogrammed station address for Yukon
controllers so overriding station address with ifconfig(8) was not
possible.
Fix the bug by reprogramming all registers that control station
address, flow-control and virtual station address. Virtual station
address has no use at this moment since driver does not make use of
fail over feature.

the IEEE80211_C_RATECTL flag set, default to NONE for all drivers. Only if
a driver calls ieee80211_ratectl_init() check if the NONE algo is still
selected and try to use AMRR in that case. Drivers are still free to use
any other algo by calling ieee80211_ratectl_set() prior to the
ieee80211_ratectl_init() call.
After this change it is now safe to assume that a ratectl algo is always
available and selected, which renders the IEEE80211_C_RATECTL flag pretty
much useless. Therefore revert r211314 and 211546.

ZTE STOR eject. This prevented my ZTE MF626 dongle from switching.
- Apply both eject methods for ZTE STOR based devices. Works on my as
well as mav's device.
- Remove the duplicate.
- Sort the usbdevs entries for Qualcomm so this won't happen again.
- Add bootverbose message displaying the fact that we are ejecting (and
how).

copied as a template for _SRS, a string pointer for descriptor name is also
copied and it becomes stale as soon as it gets de-allocated[2]. Now _CRS is
used as a template for _SRS as ACPI specification suggests if it is usable.
The template from _PRS is still utilized but only when _CRS is not available
or broken. To avoid use-after-free the problem in this case, however, only
mandatory fields are copied, optional data is removed, and structure length
is adjusted accordingly.
