intel x553 SFP+ ixgbe no go on PVE8

Did you do a make AND
make install

Then reboot?

I'll assume this was directed at me. Yes, I did. I haven't been able to find a combination that achieves ~10/~10 Gbps in both directions. Usually incoming is fine but outgoing is ridiculously low which is just... odd. It implies the optics are fine, the ones I have are just generic 10GTeks and that it's a definite driver issue, which is also backed up by the fact older kernels seem to have worked mostly fine. I'm half tempted to install RHEL on the machine and benchmark it to see if the issue goes away. That'd at least give me a starting place for figuring out what changed.

Hi,

I tested it on my ATOM C3958 machine with kernel 6.8.8-2-pve + ixgbe driver 5.20.9.
There were no warnings when building the driver.
The machine is connected to the switch (Mikrotik CRS317-1G-16S+RM) by the DAC cable.

The measurement results using iperf3 on the machine equipped with X710 (FreeBSD 13) are as follows.

promox# iperf3 -c nfs
(snip)
[ ID] Interval Transfer Bitrate Retr
[ 5] 0.00-10.00 sec 11.5 GBytes 9.90 Gbits/sec 0 sender
[ 5] 0.00-10.00 sec 11.5 GBytes 9.89 Gbits/sec receiver

promox# iperf3 -s
(snip)
[ ID] Interval Transfer Bitrate
[ 5] 0.00-10.06 sec 11.1 GBytes 9.44 Gbits/sec receiver

Looks like it's running at wire speed both up and down to me!

yes like I did when I reported this originally.

I've been trying to get this to work for about a week, works at 10 gbit only in one direction. Maybe the problem is switch or module dependant?
