Hello Sasha,
Following the issue I raised yesterday ([ofa-general] ibsim:
sim_read_pkt: write failed: Resource temporarily unavailable - pkt
dropped), I wrote a small patch that fixes the issue (in attachment).
All my tests are now running fine with this patch. Please let me know if
you have any comments ;-)
Cheers,
Vincent
