Hi, I have last driver ixgbe-3.21.2, running on kernel 2.6.35.14
Module is loaded with this parameters:
allow_unsupported_sfp=1,1 LRO=0,0 DCA=2,2 FdirPballoc=3,3
Computer is used as router, routing about 3gbit of traffic
With set_irq_affinity.sh I have set for each RxTx queue own cpu core
I am not using Flow Director:
[root@router1 /root]# ethtool -u eth2
12 RX rings available
Total 0 rules
But on counter fdir_match is visible very much traffic:
[root@router1 /root]# ethtool -S eth2 | grep fdir
fdir_match: 3463780554
fdir_miss: 6874229294
fdir_overflow: 3771
1) I am not sure if I understand documentation, but I think, that
fdir_match may be zero if I am not using Flow Director?
2) In /proc/interrupts I can see much more interrupts on TxRx-0 queue
and TxRx-11 queue is used much less:
[root@router1 /root]# cat /proc/interrupts | grep eth2
81: 1178676913 0 0 0 0 0
0 0 0 0 0 0

Can you help me? In older version of ixgbe I have almost the same
interupts on each queue
Thank you for help
