The actual commit that change those lines is following https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=98aee70d19a7e3203649fa2078464e4f402a0ad8 So your fixes tag should be Fixes: 98aee70d19a7e ("qla2xxx: Add endianizer to max_payload_size modifier.”) And looking at the changes, I see that the frame_payload_size was changed to __le16 so this should not cause regression in your env. Interestingly this patch had fixed the regression and was originally tested on SunBlade-1000 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4e08df3f91837656c36712f559d5ce8d80852760 Can you try reverting 98aee70d19a7e and retest to confirm that this patch indeed introduced regression for you. >> Can you please provide details of the commit which introduced this regression. > > See above, there was plenty of more reworks and code shuffling, and the quoted commit is also a condensed changes of other /14 series and other scsi work, … > > Have a nice weekend, > René > >> Also when you >> resubmit this patch please use Fixes tag.
