2008-09-03ixgbe: change config srrctl to only program one register per VMDq/RSS idAlexander Duyck
This change makes it so only one srrctl register is programmed per VMDq id, and if VMDq is not enabled it is one register per RSS queue. Currently this function is working correctly for the multiqueue RSS and single queue cases, but if any advances features such as VMDq or DCB would have been enabled this function would have caused issues as it was not correct.

2008-07-18igb/ixgbe/e1000e: resolve tx multiqueue bugJeff Kirsher
With the recent changes to tx mutiqueue, igb/ixgbe/e1000e was not calling netif_tx_start_all_queues() before calling netif_tx_wake_all_queues(). This causes an issue during loading of the driver.

2008-07-17net: Use queue aware tests throughout.David S. Miller
This effectively "flips the switch" by making the core networking and multiqueue-aware drivers use the new TX multiqueue structures. Non-multiqueue drivers need no changes. The interfaces they use such as netif_stop_queue() degenerate into an operation on TX queue zero. So everything "just works" for them. Code that really wants to do "X" to all TX queues now invokes a routine that does so, such as netif_tx_wake_all_queues(), netif_tx_stop_all_queues(), etc. pktgen and netpoll required a little bit more surgery than the others. In particular the pktgen changes, whilst functional, could be largely improved. The initial check in pktgen_xmit() will sometimes check the wrong queue, which is mostly harmless. The thing to do is probably to invoke fill_packet() earlier. The bulk of the netpoll changes is to make the code operate solely on the TX queue indicated by by the SKB queue mapping. Setting of the SKB queue mapping is entirely confined inside of net/core/dev.c:dev_pick_tx(). If we end up needing any kind of special semantics (drops, for example) it will be implemented here. Finally, we now have a "real_num_tx_queues" which is where the driver indicates how many TX queues are actually active. With IGB changes from Jeff Kirsher. Signed-off-by: David S.

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.
