r207622:
Drop driver lock before exiting from interrupt handler.
r207623:
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.
r207638:
When VLAN hardware tagging is disabled, make sure to disable VLAN
checksum offloading as well as TSO over VLAN.
r207628:
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.
r207635:
Free entire mbuf chain instead of the first mbuf.
- Remove dead code. Calculated greatest common divisor was not used at all.
- 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.
On sparc64 obtain the initiator ID to be used for SPI HBAs from the
Open Firmware device tree in order to match what the PROM built-in
driver uses. This is especially important when netbooting Fujitsu
Siemens PRIMEPOWER250 as in that case the built-in driver isn't used
and the port facts PortSCSIID defaults to 0, conflicting with the
disk at the same address.
- On sparc64 obtain the initiator ID from the Open Firmware device tree

Fix wrong dma tag usage. Previously it used TX descriptor ring dma
tag which should be TX mbuf dma tag.
r207625:
Remove clearing RxHashTable2 register. The register is reprogrammed
in sge_rxfilter().
Make SATA XPT negotiate and enable some additional SATA features, such as:
- device initiated power management (some devices support only this way);
- Automatic Partial to Slumber Transition (more power saving);
- DMA auto-activation (expected to slightly improve performance).
More features could be added later, when hardware supports.
r207409:
Both RX_GMF_LP_THR and RX_GMF_UP_THR must be 16 bits register. If
it is 8bits register then RX FIFO size can't exceed 2KB which is
not true for almost all Yukon II controller.
r207442:
Disable non-ASF packet flushing on Yukon Extreme as vendor's driver
does. Without this change, Yukon Extreme seems to generate lots of
RX FIFO overruns even though controller has available RX buffers.
These excessive RX FIFO overruns generated lots of pause frames
which in turn killed devices plugged into switch. It seems there is
still occasional RX frame corruption on Yukon Extreme but this
change seems to fix the pause frame storm.

Enable VLAN hardware tag insertion/stripping. Due to lack of SiS190
controller, I'm not sure whether this is also applicable to SiS190
so this feature is only activated on SiS191 controller.
In theory, controller reinitialization is not needed when VLAN tag
configuration is changed, but xclin said controller was not stable
whenever toggling VLAN tag bit. To address that, sge(4)
reinitialize controller for VLAN configuration which seems to work
as expected. VLAN tag information for TX/RX descriptor and
configure bit of RxMacControl register was found by xclin.

Enable FCS stripping and padding 10 bytes bit of RX MAC control
register. Due to lack of SiS190 controller, I'm not sure whether
this is also applicable to SiS190 so this feature is only activated
on SiS191 controller.
The controller can pad 10 bytes before DMAing a received frame to
RX buffer and received bytes include the padded bytes. This padding
is very useful on strict-alignment architectures because driver
does not have to copy received frame to align IP header on 4 bytes
boundary. It also gives better RX performance on non-strict
alignment architectures. Special thanks to xclin to give me
valuable register information. Without his enthusiastic trial and
errors this wouldn't be even possible.
While I'm here tighten validity check of received frame. Controller
clears RDS_CRCOK bit when it received bad CRC frames. xclin found
that using loop back testing.

r207375:
Preserve unknown bits of RX MAC control register when driver

r207376:
Remove wrong link state chage.
r207377:
Explicitly marks SiS190 to differentiate it from SiS191.
It seems ale(4) controllers do not like to see TCP payload in the
first descriptor in TSO case. Otherwise controller can generate bad
frames during TSO. To address it, make sure to pull up ethernet +
IP + TCP header with options in first buffer. Also ensure the
buffer length of the first descriptor for TSO covers entire ethernet
+ IP + TCP with options and setup additional Tx descriptor if the
first buffer includes TCP payload.

r206445 [2]:
iwn4965_set_txpower() uses maxpwr from EEPROM to calculate the power to

Change usb devd events from fake attach to a notify. The ugen device is not a
proper device_t so it faked the devctl event to appear like one, this is now a
notify which allows more information to be passed.
We notify for both the device attach/detach and for each usb interface. A devd
rule can now match on the interface properties, including composite devices
which may have a uvideo interface and also usound and possibly uhid too.
An example to match a umass device with a scsi subclass and BBB protocol would be
notify 100 {
match "system" "USB";
match "subsystem" "INTERFACE";
match "type" "ATTACH";
match "intclass" "0x08";
match "intsubclass" "0x06";
match "intprotocol" "0x50";
action ...
};
The old attach devctl event has been retained for the moment to make merging to
8.1 easier. This was never compatible with 7.x or earlier due to the ugen regex
change needed.

Add driver for Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet.
This driver was written by Alexander Pohoyda and greatly enhanced
by Nikolay Denev. I don't have these hardwares but this driver was
tested by Nikolay Denev and xclin.
Because SiS didn't release data sheet for this controller, programming
information came from Linux driver and OpenSolaris. Unlike other open
source driver for SiS190/191, sge(4) takes full advantage of TX/RX
checksum offloading and does not require additional copy operation in
RX handler.
The controller seems to have advanced offloading features like VLAN
hardware tag insertion/stripping, TCP segmentation offload(TSO) as
well as jumbo frame support but these features are not available
yet. Special thanks to xclin <xclin<> cs dot nctu dot edu dot tw>
who sent fix for receiving VLAN oversized frames.
