* e1000e: reorganize PHY and flow control interfaceJeff Kirsher2008-03-28
| | | | | | | | | | | | | | | | | This reorganization moves the PHY status into a separate struct. Flow Control setup is moved into this struct as well and frame size away from here into the adapter struct where its inly use is. The post-link-up code is now a separate function and moved out of the watchdog function itself. This allows us to track the es2lan restart issue a bit easier.

| | | | | | | | | | | | | | Users reported that ARP's were lost with e1000e. The problem is fixed by not enabling this manageability configuration bit.

| | | | | | | | | | formerly e1000/e1000e only updated traffic counters once every 2 seconds with the register values of bytes/packets.

* e1000/e1000e: Move PCI-Express device IDs over to e1000eAuke Kok2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | e1000e will from now on support the PCI-Express adapters that previously were supported by e1000. This support means better performance and easier debugging from now on for both the old PCI-X/PCI hardware and PCI-Express adapters. This patch also moves 3 recently merged device IDs over to e1000e that are identical to quad-port versions of already existing dual port versions. With this last bit every former e1000 pci-e device should work now with e1000e. Here is a brief list of which gigabit driver to use with which adapter: e1000: 82540 -> 82547 e1000e: 82571 -> 82573 ich8, ich9 (82562 or 82566) es2lan (80003eslan) igb: (not yet merged, only available from e1000.sf.net) 82575 Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* e1000e: Disable L1 ASPM power savings for 82573 mobile variantsAuke Kok2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | L1 ASPM link (pci-e link power savings) has significant benefits (~1W savings when link is active) but unfortunately does not work correctly on any of the chipsets that have 82573 on mobile platforms which causes various nuisances: - eeprom reads return garbage information leading to bad eeprom checksums - long ping times (up to 2 seconds) - complete system hangs (freeze/lockup) A lot of T60 owners have been plagued by this, but other mobile solutions also suffer from these symptoms. Disabling L1 ASPM before we activate the PCI-E link fixes all of these issues at the cost of some power consumption. Remove a workaround RDTR adjustment that is no longer needed with this new one.

* [NET]: Fix interrupt semaphore corruption in Intel drivers.David S. Miller2008-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several of the Intel ethernet drivers keep an atomic counter used to manage when to actually hit the hardware with a disable or an enable. The way the net_rx_work() breakout logic works during a pending napi_disable() is that it simply unschedules the poll even if it still has work. This can potentially leave interrupts disabled, but that is OK because all of the drivers are about to disable interrupts anyways in all such code paths that do a napi_disable(). Unfortunately, this trips up the semaphore used here in the Intel drivers. If you hit this case, when you try to bring the interface back up it won't enable interrupts. A reload of the driver module fixes it of course. So what we do is make sure all the sequences now go: napi_disable(); atomic_set(&adapter->irq_sem, 0); *_irq_disable(); which makes sure the counter is always in the correct state.

* [NET]: Fix TX timeout regression in Intel drivers.David S. Miller2008-01-17
| | | | | | | | | | | | | | This fixes a regression added by changeset 53e52c729cc169db82a6105fac7a166e10c2ec36 ("[NET]: Make ->poll() breakout consistent in Intel ethernet drivers.") As pointed out by Jesse Brandeburg, for three of the drivers edited above there is breakout logic in the *_clean_tx_irq() code to prevent running TX reclaim forever. If this occurs, we have to elide NAPI poll completion or else those TX events will never be serviced. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Jesse Brandeburg <jesse.brandeburg@intel.com>
* [NET]: Make ->poll() breakout consistent in Intel ethernet drivers.David S. Miller2008-01-09
| | | | | | | | | | | | | | | | This makes the ->poll() routines of the E100, E1000, E1000E, IXGB, and IXGBE drivers complete ->poll() consistently. Now they will all break out when the amount of RX work done is less than 'budget'. At a later time, we may want put back code to include the TX work as well (as at least one other NAPI driver does, but by in large NAPI drivers do not do this). But if so, it should be done consistently across the board to all of these drivers. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Auke Kok <auke-jan.h.kok@intel.com>
* [NET]: Do not check netif_running() and carrier state in ->poll()David S. Miller2008-01-09
| | | | | | | | | | Drivers do this to try to break out of the ->poll()'ing loop when the device is being brought administratively down. Now that we have a napi_disable() "pending" state we are going to solve that problem generically. Signed-off-by: David S. Miller <davem@davemloft.net>
* e1000e: Remove legacy jumbo frame receive codeAuke Kok2007-10-29

* e1000e: Re-enable SECRC - crc strippingAuke Kok2007-10-29
| | | | | | | | | | | This workaround code performed software stripping instead of the hardware which can do it much faster. None of the e1000e target hardware has issues with this feature and should work fine. This gives us some performance back on receive, and removes some kludging stripping the 4 bytes.

* e1000e: Fix PBA calculation for jumbo frame packetsAuke Kok2007-10-29
| | | | | | | | | | | | | | Upon inspection the rx FIFO size calculation code was found to have 2 significant flaws: A superfluous minus sign resulting in the wrong size to be used for jumbo frames on 82573 and ich9, as well as that this code rewrote the read-only adapter->pba variable resulting in different values at each run. Without this patch jumbo's will work but performance will be awkward since the TX size is not adequate for two whole frames.

* e1000e: Fix jumbo frame receive code.Auke Kok2007-10-29
| | | | | | | | | | | | | | | | Fix allocation and freeing of jumbo frames where several bugs were recently introduced by cleanups after we forked this code from e1000. This moves ps_pages to buffer_info where it really belongs and makes it a dynamically allocated array. The penalty is not that high since it's allocated outside of the buffer_info struct anyway. Without this patch all jumbo frames are completely broken and the driver panics.

| | | | | | | | | | | After a cable unplug the forced flow control settings were lost accidentally and the flow control settings fell back to the default EEPROM determined values.

* [E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)Auke Kok2007-10-10
This driver implements support for the ICH9 on-board LAN ethernet device. The device is similar to ICH8. The driver encompasses code to support 82571/2/3, es2lan and ICH8 devices as well, but those device IDs are disabled and will be "lifted" from the e1000 driver over one at a time once this driver receives some more live time. Changes to the last snapshot posted are exclusively in the internal hardware API organization. Many thanks to Jeff Garzik for jumping in and getting this organized with a keen eye on the future layout.
