2009-03-20net: reorder struct Qdisc for better SMP performanceEric Dumazet
dev_queue_xmit() needs to dirty fields "state", "q", "bstats" and "qstats" On x86_64 arch, they currently span three cache lines, involving more cache line ping pongs than necessary, making longer holding of queue spinlock. We can reduce this to one cache line, by grouping all read-mostly fields at the beginning of structure. (Or should I say, all highly modified fields at the end :) ) Before patch : offsetof(struct Qdisc, state)=0x38 offsetof(struct Qdisc, q)=0x48 offsetof(struct Qdisc, bstats)=0x80 offsetof(struct Qdisc, qstats)=0x90 sizeof(struct Qdisc)=0xc8 After patch : offsetof(struct Qdisc, state)=0x80 offsetof(struct Qdisc, q)=0x88 offsetof(struct Qdisc, bstats)=0xa0 offsetof(struct Qdisc, qstats)=0xac sizeof(struct Qdisc)=0xc0 Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2009-03-20ixgbe: Fixup the watchdog interrupt scheduling on 82599Jesse Brandeburg
The watchdog will schedule an interrupt to help make sure queues are cleaned in the case when an interrupt is missed, most likely due to very high load. On 82599, there are extra interrupt registers to account for the larger number of MSI-X vectors (64 total for 82599 vs. 18 total for 82598). These must be taken into account when performing this operation in the watchdog.

2009-03-20e1000e: allow tx of pre-formatted vlan tagged packetsArthur Jones
As with igb, when the e1000e driver is fed 802.1q packets with hardware checksum on, it chokes with an error of the form: checksum_partial proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out wiht the correct hardware checksum. Thanks to Kand Ly <kand@riverbed.com> for discovering the issue and the coming up with a solution.

2009-03-18smsc911x: reset last known duplex and carrier on openSteve Glendinning
smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.

2009-03-18tulip: fix crash on iface up with shirq debugKyle McMartin
Tulip is currently doing request_irq before it has done its initialization. This is usually not a problem because it hasn't enable interrupts yet, but with DEBUG_SHIRQ on, we call the irq handler when registering the interrupt as a sanity check. This can result in a NULL ptr dereference, so call tulip_init_ring before request_irq, and add a free_ring function to do the freeing now shared with tulip_close. Tested with a shell loop running ifup, ifdown in a loop a few hundred times with DEBUG_SHIRQ on. Signed-off-by: Kyle McMartin <kyle@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-18virtio_net: Make virtio_net support carrier detectionPantelis Koukousoulas
Impact: Make NetworkManager work with virtio_net For now the semantics are simple: There is always carrier. This allows a seamless experience with e.g., qemu/kvm where NetworkManager just configures and sets up everything automagically. If/when a generally agreed-upon way to control carrier on/off in the emulator/hypervisor level emerges, it will be trivial to extend the driver to support that too, but for now even this 2-liner makes user experience that much better.

Fix the behavior of allowing both sysctl and addrconf_dad_failure() to set the disable_ipv6 parameter without any bad side-effects. If DAD fails and accept_dad > 1, we will still set disable_ipv6=1, but then instead of allowing an RA to add an address then immediately fail DAD, we simply don't allow the address to be added in the first place.

2009-03-18bnx2: Fix problem of using wrong IRQ handler.Michael Chan
The MSI-X handler was chosen before the call to pci_enable_msix(). If MSI-X was not available, the wrong MSI-X handler would be used in INTA mode. This would cause a screaming interrupt problem because INTA would not be cleared by the MSI-X handler. Fixed by assigning MSI-X handler after pci_enable_msix() returns successfully.
