https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242890 --- Comment #3 from Patrick Kelsey <pkelsey@freebsd.org> --- (In reply to Andriy Gapon from comment #2) When I converted the vmxnet3 driver to iflib, I enabled the RSS code based = on iflib internals and looking sideways at the bnxt driver, and not so much by thinking through the RSS code's fundamental requirements. What I saw in the bnxt driver was that it was setting the RSS key using arc4rand() in bnxt_attach_pre(), and that it is always using the hash value= for the flowid in bnxt_pkt_get_l2(). That lead me to believe that the rss key value did not have to be anything specific, and is why the way the vmxnet3 = code behaves with respect to this issue is functionally the same as what bnxt do= es. If I am not missing something further, perhaps this same issue exists for t= he bnxt driver as well. --=20 You are receiving this mail because: You are the assignee for the bug.=
