* sky2: restore multicast list on resume and other opsStephen Hemminger2007-09-131-1/+8
| | | | | | | Need to restore multicast settings on resume and after 'ethtool -r'. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2 1.17Stephen Hemminger2007-08-251-1/+1
| | | | | | | Mark new version to track if current driver is in use. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: only bring up watchdog if link is activeStephen Hemminger2007-08-251-30/+25
| | | | | | | | | | | This fixes the extra timer overhead that people were whining about as a 2.6.23 regression. Running the watchdog timer all the time is unneeded. Change it to run only if link is up, and reduce frequency to save power. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: clear PCI power control reg at startupStephen Hemminger2007-08-251-1/+6
| | | | | | | | Make sure PCI register for PHY power gets cleared on boot, and make sure to avoid any PCI posting problems. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: don't clear phy power bitsStephen Hemminger2007-08-211-2/+2
| | | | | | | | | There are special PHY settings available on Yukon EC-U chip that should not get cleared. This should solve mysterious errors on some motherboards (like Gigabyte DS-3).

* [NET]: ethtool_perm_addr only has one implementationMatthew Wilcox2007-07-311-1/+0
| | | | | | | | | All drivers implement ethtool get_perm_addr the same way -- by calling the generic function. So we can inline the generic function into the caller and avoid going through the drivers. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: David S. Miller <davem@davemloft.net>
* Fix up sky2 breakageAl Viro2007-07-201-3/+4
| | | | | | | | | | Doing |= 1 << 19 to 16bit unsigned is not particulary useful; that register is 32bit, unlike the ones dealt with in the rest of function, so we need u32 variable here.

* sky2: check drop truncated packetsStephen Hemminger2007-07-101-0/+8
| | | | | | | | If packet larger than MTU is received, the driver uses hardware to truncate the packet. Use the status registers to catch/drop them. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: add support for read/write of EEPROMStephen Hemminger2007-07-101-25/+115

* sky2: receive fillStephen Hemminger2007-07-101-22/+14
| | | | | | | | Simplify receive buffer refill logic. Rather than trying to update incrementally; do receive ring refill at end of receive processing. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: check for more work before leaving NAPIStephen Hemminger2007-07-101-18/+17
| | | | | | | | | This patch avoids generating another IRQ if more packets arrive while in the NAPI poll routine. Before marking device as finished, it rechecks that the status ring is empty.

* sky2: debug interfaceStephen Hemminger2007-07-101-2/+194
| | | | | | | | Add an optional debug interface for displaying state of transmit/receive rings. Creates a file debugfs/sky2/ethX for each device that is up. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: carrier managementStephen Hemminger2007-07-101-7/+4

* sky2: restore workarounds for lost interruptsStephen Hemminger2007-07-101-1/+8
| | | | | | | | | | | This patch restores a couple of workarounds from 2.6.16: * restart transmit moderation timer in case it expires during IRQ routine * default to having 10 HZ watchdog timer. At this point it more important not to hang than to worry about the power cost. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | Enable support for Yukon EX chipset (88e8071). Most of changes are related to new commands to chip for transmit, and change in status and checksumming. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: GPIO registerStephen Hemminger2007-07-091-0/+5

* sky2: enable clocks before probeStephen Hemminger2007-07-091-4/+3
| | | | | | | | Catch-22: On Yukon EX (88E8071) need to have internal clocks enabled before reading chip id. It is harmless on other chips. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: rename BMU registerStephen Hemminger2007-07-091-1/+1
| | | | | | | | This register is more of a test and control register on Yukon2. So rename it to Q_TEST and give some bit definitions. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: Add PCI device specfic register 4 & 5Stephen Hemminger2007-07-091-6/+12

* sky2: avoid reserved regions on ethtool reg dumpStephen Hemminger2007-07-091-5/+9
| | | | | | | | | On Yukon EX reading some of the undocumented places in the memory space will cause a hang. Since they don't provide useful information, just skip the reserved areas. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | Fix sky2 disabling VLAN completely when the first vid is unregistered. sky2 disables VLAN completely when the first VID is unregistered. It should instead disable VLAN when the group is unregistered by calling sky2_vlan_rx_register with grp = NULL.

* sky2: dont set bogus bit in PHY registerStephen Hemminger2007-05-301-1/+1
| | | | | | | | | | This code inherited from the sk98lin driver is incorrect on the Yukon2. The GPHY_CTRL register values are specific to the internal PHY of the chip and the values used were leftovers. Driver was setting bit 13 which is now the INT polarity for the PHY!

* sky2: memory barriers changeStephen Hemminger2007-05-181-4/+11
| | | | | | | | | Do some memory barrier changes for safety/perfomance: Don't need read after update to index, mmiowb() followed by read at end of irq is sufficient. Signed-off-by: Stephn Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: remove dual port workaroundStephen Hemminger2007-05-181-7/+0
| | | | | | | | | | This workaround was added to deal with NAPI core and how it affected dual port shared polling. It turned out not to be necessary. Stopping device 0 only doesn't stop NAPI from working completely after that. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* sky2: PHY register settingsStephen Hemminger2007-05-181-1/+6
| | | | | | | | | | | Align the PHY setup of the sky2 driver with the vendor sk98lin (10.0.4.3) driver. The PHY register settings are mostly black magic, even with access to the documentation it isn't clear what the right values are. The changes are mostly comments, the code change only affects the Yukon FE (100 mbit only) version.

* sky2: 88e8071 support not readyStephen Hemminger2007-05-111-1/+1
| | | | | | | | | | The driver is not ready to support 88e8071 chip. If this chip is present, system will hang on boot. So remove it from PCI device id's for now. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sky2: fix oops on shutdownStephen Hemminger2007-05-111-0/+10
| | | | | | | | | If the device is fails during module startup for some reason like unsupported chip version then the driver would crash dereferencing a null pointer, on shutdown or suspend/resume.

* sky2: EC-U performance and jumbo supportStephen Hemminger2007-04-191-25/+60
| | | | | | | | | | | | | The Yukon EC Ultra chips have transmit settings for store and forward and PCI buffering. By setting these appropriately, normal performance goes from 750Mbytes/sec to 940Mbytes/sec (non-jumbo). It is also possible to do Jumbo mode, but it means turning off TSO and checksum offload so the performance gets worse. There isn't enough buffering for checksum offload to work.
