#59 Unable to compile ISCSI module on 5.15 kernel with ISER
Hello SCST team,
I have server on Ubuntu 20.04. The system uses HWE kernel 5.15
The server has few mellanox-6 network cards with MOFED 5.6 drivers
When I try to build iscsi module it always failed with infiband errors
Could you fix that?
Thank you.

Hi,
Thank you for the report. I will take a look at it soon.
