2011-03-16Handle irq assignment on multiqueue NICStephen Hemminger
Bug 6845, 6821 Need to avoid using /sys/class/net/ethX/device/irq (or /sys/bus/pci/.../irq) because these don't handle MSI or multiqueue. This also resolves issues with Vmware/ESX.

Bug 6845 Warn (and ignore) attempt to assign IRQ directly on multiqueuej NIC.
2011-02-25Don't set irq affinity if device is disabledStephen Hemminger
Bug 6784 No point in trying to force affinity if device is offline.

2010-12-22Affinity script was failing to configure some queues of multi-queue NICs.Bob Gilligan
The problem was due to incorrect initialization of the $q and $cpu variables. Their initializations were reversed.
2010-11-12Fix irq-affinity for special casesStephen Hemminger
Need to handle virtual devices with no IRQ, and older processors without concept of multi-core.
2010-11-12New IRQ affinity script and RPS supportStephen Hemminger
Replace old script with new cleaner script that handles both IRQ affinity and Receive Packet Steering. Instead of two scripts (one for mask and one for auto), do it all with one script. Receive Packet Steering is supported in two ways. If 'auto' is used, then both threads on HT system will be used for receive processing. If explicit mask is given, then two masks can be used to set both IRQ cpus and RPS cpus.
