Hi all, I was able to trigger the same issue as reported by Paul, and came across this patch (+ Daniele's other patch and thread on the libqmi mailing list). Applying Paul's fix solved the problem for me, changing the MTU of the QMI interface now works fine. Thanks a lot to everyone involved!
I just have one question, is there a specific reason for the patch not being resubmitted or Daniele's work not resumed? I do not use any of the aggregation-stuff, so I don't know how that is affected by for example Paul's change. If there is anything I can do to help, please let me know. BR, Kristian
