* ixgbe: ixgbe_down needs to stop dev_watchdogJohn Fastabend2010-04-27
| | | | | | | | | | | | | | | | | | | | | There is a small race between when the tx queues are stopped and when netif_carrier_off() is called in ixgbe_down. If the dev_watchdog() timer fires during this time it is possible for a false tx timeout to occur. This patch moves the netif_carrier_off() so that it is called before the tx queues are stopped preventing the dev_watchdog timer from detecting false tx timeouts. The race is seen occosionally when FCoE or DCB settings are being configured or changed. Testing note, running ifconfig up/down will not reproduce this issue because dev_open/dev_close call dev_deactivate() and then dev_activate().

* ixgbe: enable extremely low latencyJesse Brandeburg2010-04-27
| | | | | | | | | | | | | | | 82598/82599 can support EITR == 0, which allows for the absolutely lowest latency setting in the hardware. This disables writeback batching and anything else that relies upon a delayed interrupt. This patch enables the feature of "override" when a user sets rx-usecs to zero, the driver will respect that setting over using RSC, and automatically disable RSC. If rx-usecs is used to set the EITR value to 0, then the driver should disable LRO (aka RSC) internally until EITR is set to non-zero again.

* TCP: avoid to send keepalive probes if receiving dataFlavio Leitner2010-04-27
| | | | | | | | | | | | | | | | | | | RFC 1122 says the following: ... Keep-alive packets MUST only be sent when no data or acknowledgement packets have been received for the connection within an interval. ...

| * e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errataBruce Allan2010-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>, further digging into errata documentation reveals the current enabling or disabling of ASPM L0s and L1 states for certain parts supported by this driver are incorrect. 82571 and 82572 should always disable L1. For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The issue raises when having 2 NICs both assigned the same IPv6 global address. If a sender binds to a particular NIC (SO_BINDTODEVICE), the outgoing traffic is being sent via the first found. The bonded device is thus not taken into an account during the routing. From the ip6_route_output function: If the binding address is multicast, linklocal or loopback, the RT6_LOOKUP_F_IFACE bit is set, but not for global address. So binding global address will neglect SO_BINDTODEVICE-binded device, because the fib6_rule_lookup function path won't check for the flowi::oif field and take first route that fits.

* | sky2: add support for receive hashingStephen Hemminger2010-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Sky2 hardware supports hardware receive hash calculation. Now that Receive Packet Steering is available, add support to enable it. This version does not depend on CONFIG_RPS. Also set_flags rejects all values except RXHASH, so driver won't have to change next time somebody adds a new one.
