2008-03-17pata_ali: use atapi_cmd_type() to determine cmd type instead of transfer sizeTejun Heo
pata_ali was using qc->nbytes to determine whether a command is data transfer type or not. As now qc->nbytes can be extended by padding and draining buffers, these tests are not useful anymore.

ahci is often implemented with accompanying SFF compatible interface and legacy IDE driver may attach to the legacy IO ports when the controller is already claimed by ahci and vice-versa.

Improve ACPI hotplug handling such that dock event is handled properly. * Register handlers for dock events. * Directly detach device on EJECT_REQUEST instead of signaling hotplug event. This prevents libata from accessing severed controller and/or device. * While at it, use named constants for ACPI events and move uevent signaling inside host lock.

2008-03-17forcedeth: limit tx to 16Ayaz Abdulla
This is a critical patch which adds a workaround for a HW bug. The patch will limit the number of outstanding tx packets to 16. Otherwise, the HW could send out packets with bad checksums. The driver will still setup the tx packets into the ring, however, will only set the Valid bit on 16 packets at a time.

2008-03-17cxgb3: Fix transmit queue stop mechanismDivy Le Ray
The last change in the Tx queue stop mechanism opens a window where the Tx queue might be stopped after pending credits returned. Tx credits are returned via a control message generated by the HW. It returns tx credits on demand, triggered by a completion bit set in selective transmit packet headers. The current code can lead to the Tx queue stopped with all pending credits returned, and the current frame not triggering a credit return. The Tx queue will then never be awaken. The driver could alternatively request a completion for packets that stop the queue. It's however safer at this point to go back to the pre-existing behaviour.

2008-03-17rndis_host: fix transfer size negotiationJean-Christophe Dubois
This patch should resolve a problem that's troubled support for some RNDIS peripherals. It seems to have boiled down to using a variable to establish transfer size limits before it was assigned, which caused those devices to fallback to a default "jumbogram" mode we don't support. Fix by assigning it earlier for RNDIS.

2008-03-17NEWEMAC: fix support for pause packetsPravin M. Bathija
Problem Description and Fix --------------------------- When a pause packet(with destination as reserved Multicast address) is received by the EMAC hardware to control the flow of frames being transmitted by it, it is dropped by the hardware unless the reserved Multicast address is hashed in to the GAHT[1-4] registers. This code fix adds the default reserved multicast address to the GAHT[1-4] registers in the EMAC(s) present on the chip. The flow control with Pause packets will only work if the following register bits are programmed in EMAC: EMACx_MR1[APP] = 1 EMACx_RMR[BAE] = 1 EMACx_RMR[MAE] = 1 Behavior that may be observed in a running system ------------------------------------------------- A host transferring data from a PPC based system may send a Pause packet to the PPC EMAC requesting it to slow down the flow of packets. If the default reserved multicast MAC address is not programmed into the GAHT[1-4] registers this Pause packet will be dropped by PPC EMAC and no Flow Control will be done. Signed-off-by: Pravin M.

I think its the following race: poll says netif_rx_complete poll calls enable_cb enable_cb opens the interrupt mask a new packet comes, an interrupt is triggered----\ enable_cb sees that there is more work | enable_cb disables the interrupt | . V . interrupt is delivered . skb_recv_done does atomic napi test, ok some waiting disable_cb is called->check fails->bang! . poll would do napi check poll would do disable_cb The fix is to let enable_cb not disable the interrupt again, but expect the caller to do the cleanup if it returns false. In that case, the interrupt is only disabled, if the napi test_set_bit was successful.

2008-03-17ixgbe: Introduce adaptive interrupt moderationAyyappan Veeraiyan
82598 can produce a formidable interrupt rate, and is largely unusable without some form of moderation. The default behaviour before this patch is to limit irq's to a reasonable number. However, just like our other drivers we can reduce latency for small packet-type traffic considerably by allowing the irq rate to go up dynamically. This patch introduces a simple irq moderation algorithm based on traffic analysis. The driver will use more CPU to service small packets quicker but will perform the same on bulk traffic as the old code.

2008-03-17ixgbe: Introduce MSI-X queue vector codeAyyappan Veeraiyan
This code abstracts the per-queue MSI-X interrupt vector into a queue vector layer. This abstraction is needed since there can be many more queues than available MSI-X vectors in a machine. The MSI-X irq vectors are remapped to a shared queue vector which can point to several (both RX and TX) hardware queues. The NAPI algorithm then cleans the appropriate ring/queues on interrupt or poll. The remapping is a delicate and complex calculation to make sure that we're not unbalancing the irq load, and spreads the irqs as much as possible, and may combine RX and TX flows onto the same queue vector. This effectively enables receive flow hashing across vectors and helps irq load balance across CPUs.
