[Etherlab-users] Scan Rate Differnces between ec_igb and ec_igc

[Mike O'Connor]

Hi All

I've been working on a new standard installation for our machines, and 
one of the boxes I'm testing is a DIN rail unit with three Ethernet, two 
igb port and one igc port.

During my testing I tried the igb and igc for the EtherCAT interface and 
found that the igc can transmit much faster than the igb has datagram 
UNMATCHED! messages even at 1000 packets per second.

The igc can do 4000 packets without any of these messages, and very few 
at 8000 packets.

I'm using a 6.6.11 kernel with  PREEMPT_DYNAMIC and the driver packages 
provided from 
https://mirrorcache-au.opensuse.org/repositories/science:/EtherLab/Debian_12/

Any ideas?

Mike
