Hello Ozkan,

Thank you very much for your comment! I have not seen any failures in tx/rx or
tx/tx configurations since setting hw.ixl.enable_head_writeback=0. Now that I
know what to search for, I found multiple posts suggesting setting that sysctl
to zero for better stability. I agree it would be preferable to not require
manual adjustments to ixl.
