2010-09-26de2104x: fix TP link detectionOndrej Zary
Compex FreedomLine 32 PnP-PCI2 cards have only TP and BNC connectors but the SROM contains AUI port too. When TP loses link, the driver switches to non-existing AUI port (which reports that carrier is always present). Connecting TP back generates LinkPass interrupt but de_media_interrupt() is broken - it only updates the link state of currently connected media, ignoring the fact that LinkPass and LinkFail bits of MacStatus register belong to the TP port only (the chip documentation says that). This patch changes de_media_interrupt() to switch media to TP when link goes up (and media type is not locked) and also to update the link state only when the TP port is used. Also the NonselPortActive (and also SelPortActive) bits of SIAStatus register need to be cleared (by writing 1) after reading or they're useless.

2010-09-26de2104x: fix power managementOndrej Zary
At least my 21041 cards come out of suspend with bus mastering disabled so they did not work after resume(no data transferred). After adding pci_set_master(), the driver oopsed immediately on resume - because de_clean_rings() is called on suspend but de_init_rings() call was missing in resume. Also disable link (reset SIA) before sleep (de4x5 does this too). Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Acked-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: David S.

2010-09-25ixgbevf: Refactor ring parameter re-sizeGreg Rose
The function to resize the Tx/Rx rings had the potential to dereference a NULL pointer and the code would attempt to resize the Tx ring even if the Rx ring allocation had failed. This would cause some confusion in the return code semantics. Fixed up to just unwind the allocations if any of them fail and return an error.

2010-09-25de2104x: disable autonegotiation on broken hardwareOndrej Zary
At least on older 21041-AA chips (mine is rev. 11), TP duplex autonegotiation causes the card not to work at all (link is up but no packets are transmitted). de4x5 disables autonegotiation completely. But it seems to work on newer (21041-PA rev. 21) so disable it only on rev<20 chips.

2010-09-23e1000: fix occasional panic on unloadJesse Brandeburg
Net drivers in general have an issue where timers fired by mod_timer or work threads with schedule_work are running outside of the rtnl_lock. With no other lock protection these routines are vulnerable to races with driver unload or reset paths. The longer term solution to this might be a redesign with safer locks being taken in the driver to guarantee no reentrance, but for now a safe and effective fix is to take the rtnl_lock in these routines.

If the netdev->features is set with NETIF_F_HIGHDMA, we should set the corresponding netdev->vlan_features as well to allow VLAN netdev created on top of the real netdev to be able to also benefit from HIGHDMA on 32bit system, reducing the performance hit that is caused by __skb_linearize(), particularly for large send.

2010-09-23e1000e: 82579 do not gate auto config of PHY by hardware during nominal useBruce Allan
For non-managed versions of 82579, set the bit that prevents the hardware from automatically configuring the PHY after resets only when the driver performs a reset, clear the bit after resets. This is so the hardware can configure the PHY automatically when the part is reset in a manner that is not controlled by the driver (e.g. in a virtual environment via PCI FLR) otherwise the PHY will be mis-configured causing issues such as failing to link at 1000Mbps. For managed versions of 82579, keep the previous behavior since the manageability firmware will handle the PHY configuration.

2010-09-23e1000e: 82579 jumbo frame workaround causing CRC errorsBruce Allan
The subject workaround was causing CRC errors due to writing the wrong register with updates of the RCTL register. It was also found that the workaround function which modifies the RCTL register was being called in the middle of a read-modify-write operation of the RCTL register, so the function call has been moved appropriately. Lastly, jumbo frames must not be allowed when CRC stripping is disabled by a module parameter because the workaround requires the CRC be stripped.

2010-09-23e1000e: 82579 unaccounted missed packetsBruce Allan
On 82579, there is a hardware bug that can cause received packets to not get transferred from the PHY to the MAC due to K1 (a power saving feature of the PHY-MAC interconnect similar to ASPM L1). Since the MAC controls the accounting of missed packets, these will go unnoticed. Workaround the issue by setting the K1 beacon duration according to the link speed.

2010-09-23e1000e: 82579 SMBus address and LEDs incorrect after device resetBruce Allan
Since the hardware is prevented from performing automatic PHY configuration (the driver does it instead), the OEM_WRITE_ENABLE bit in the EXTCNF_CTRL register will not get cleared preventing the SMBus address and the LED configuration to be written to the PHY registers.

When going to Sx, disable gigabit in PHY (e1000_oem_bits_config_ich8lan) in addition to the MAC before configuring PHY wakeup otherwise the PHY configuration writes might be missed. Also write the LED configuration and SMBus address to the PHY registers (e1000_oem_bits_config_ich8lan and e1000_write_smbus_addr, respectively). The reset is no longer needed since re-auto-negotiation is forced in e1000_oem_bits_config_ich8lan and leaving it in causes issues with auto-negotiating the link.
