Hi All
I’m looking for a nice way to pass parameters (list of integers) to each
ixgbe interface.
Creating /sys entries seems too complex and so I thought about ethtool.
How can I pass private data (a list) to each nic with minimal driver code
change ?
To clarify, I want to use a customized affinity hint with multi queue.
For example, on a machine with 12 cores and RSS of 4 I want to set the
RX/TX queues to CPUs 8-11, It would look something like:
ethtool –set-cpu eth0 8 9 10 11 #to set the affinity hint for the first 4
queues to cpus 8-11
ethtool –set-channels eth0 combined 4 #Recreate 4 Rx/Tx vectors and use the
new and customized affinity hint.
<Set the regular RX IRQ affinity to the same CPUs>
Your help is much appreciated !
Thanks,
Tal Abudi.
