2011-05-20	irq-affinity: more fixup	Stephen Hemminger
	1. Fix thread_per_core -- now a global variable 2. Add documentation about where still broken with offline cpus 3. Break out hamming weight function (might be used to fix #2) Tested on UP, 4 core x 2 thread, 8 socket (virt) and Multiqueue and single queue NIC.
2011-05-20	irq-affinity: use sysfs to read cpu topology	Stephen Hemminger
	Change to using sysfs to read cpu topology. This makes code more robust and follow the standard practice of other utilities. As an added benefit, irq-affinty now handles offline cpu's and other cases where cpu numbers are not fully populated.
2011-05-20	irq-affinity: initialize sockets to 1	Stephen Hemminger

2011-05-19	irq-affinity: fix handling of UP system	Stephen Hemminger
	On a UP system, there is no "physical-id" in /proc/cpuinfo.
2011-05-19	Use syslog perror for debug option	Stephen Hemminger
	Rather than reinventing existing code, use library.
2011-05-17	Bugfix: 6773 (again). Fix handling of single-queue NICs on MPs.	Bob Gilligan
	Some single-queue NICs use the multiqueue IRQ naming format (e.g. eth0-rx-0). We need to select the CPU assignements for these IRQs using the same algorithm that we use for single-queue NICs using the standard naming format (e.g. eth0).
2011-05-17	Fix calculation of number of cores on systems with more than one socket.	Bob Gilligan

2011-05-17	Support more than 10 CPUs.	Bob Gilligan

2011-05-17	irq-affinity: add workaround to avoid some cpu's	Stephen Hemminger
	For routing and other applications it is helpful to provide some mechanism to reserve some set of CPU's and not assign interface IRQ's to them. Uses environment variable VYATTA_IRQAFFINITY_BANNED_CPUS as mechanism similar to irqbalance(8).
2011-05-16	smp-affinity: fix typo for assign_multiqueue	Stephen Hemminger
	Multiqueue setup was broken ixgbe because of s/assign/assing/
2011-05-06	Support netxen NIC irq naming convention	Stephen Hemminger
	Bug 7062 The irq's on Netxen NIC are named: eth0[0] eth0[1] eth0[2] ... This confuses the auto IRQ affinity script.
2011-05-03	Make irq affinity handle any irq naming convention	Stephen Hemminger
	Bug 7032 (reprise) Since there are various forms of multi-queue naming, it is better to just go with the simplest pattern which is to take all the irq's of form ethX-... and sort them.
2011-05-02	Fix irq-affinity mapping for multiqueue NIC's	Stephen Hemminger
	Bug 7032 Fix matchinging of irq's named 'eth0-TxRx-0'. And change the code to handle any form of IRQ naming of multiqueue that is eth0-xxx-0.
2011-04-13	fix typo in irq-affinity	Stephen Hemminger

2011-04-13	Fix irq naming convention mapping code	Stephen Hemminger
	The mislabeled commit ddce08161907797fe914ba609b362d812e23fc8a Fix wrong name in get_irq_affinity Was some code to handle Broadcom device IRQ naming convention that was untested. The part that built regex was incorrectly expanding a string with regex characters.
2011-04-10	Fix wrong name in get_irq_affinity	Stephen Hemminger

2011-03-16	Handle irq assignment on multiqueue NIC	Stephen 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.
2011-03-01	Warn if attempting to force mask on multiqueue NIC	Stephen Hemminger
	Bug 6845 Warn (and ignore) attempt to assign IRQ directly on multiqueuej NIC.
2011-02-25	Don't set irq affinity if device is disabled	Stephen Hemminger
	Bug 6784 No point in trying to force affinity if device is offline.
2011-02-22	Handle Vmware mulitqueue naming convention	Stephen Hemminger
	Adapt to irq naming convention in 2.6.37 kernel for vmxnet3 driver.
2011-02-21	Handle case of device with no active IRQ	Stephen Hemminger
	Bug 6784 Disabled device has no IRQ, so don't change it.
2011-02-03	Bugfix 6773: Spread load of single-queue NICs across all CPUs.	Bob Gilligan
	The initial CPU selection function needs to take hyperthreading into account.
2011-01-31	Fix grammar error in help string.	Robert Bays
	(cherry picked from commit a943568e64bca73bb2951e968d0cc752d72874ab)
2010-12-22	Affinity 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.
2010-11-12	Fix irq-affinity for special cases	Stephen Hemminger
	Need to handle virtual devices with no IRQ, and older processors without concept of multi-core.
2010-11-12	New IRQ affinity script and RPS support	Stephen 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.
