You could try disabling EEE (Energy Efficient Ethernet). Something
like: sysctl dev.igc.0.eee_control=0.
It does not seem to make a difference. If I have the FC as default, I
get the link bounce on the 2.5G xover (cat 6 cable) maybe 2-3 min in
running iper3 tests. However, if I disable all flow control
dev.igc.0.fc=0
dev.igc.1.fc=0
dev.igc.2.fc=0
dev.igc.3.fc=0
It *seems* to be less frequent but still happens. I ordered a 2.5 G
switch so I can try and at least see which side is dropping the link.
Should have it Friday to continue testing
OK, I repeated the tests with a 2.5G unmanaged switch in between the two
units rather than xover. It looks like its the server that is sending
the majority of the packets that drops the link, not the receiver.
One other test I did was to up hw.igc.max_interrupt_rate=13000 from the
default of 8000. That seems to make the problem MUCH more acute.
Here is the before and after of the link drop.
