Hi list,
Here is a very small patch to enable the use of "ethtool --show-rxfh" and
"ethtool --set-rxfh" with ixgbe. I've tested it with my X520 cards, but it
should be good with all cards as it's kind of a simple merge from igb and
the existing code for initialisation of the rx indirection table in ixgbe...
If someone would need use cases :
- Allow changing the number of queue used for RSS whithout resetting. To
let more queues available for flow director, or because straffic slowed
down and you want more cores to go to sleep.
- Use the weight mode of ethtool to dynamicly load balance flows
overwhelming some queues.
Thanks for your review,
