well, I just expected to see master media option documented somewhere, to make it clear what is "trunk master" and what is "clocking master". > >> > lacp hashing policy is the same as for loadbalance, see the manpage and >> > confirm in trunk_hashmbuf(). >> >> I see different inbound packet distribution on trunk on-top of em(4)s >> and on trunk on top of bnx(4)s - >> that's the real problem. > > The trunk driver can't influence inbound packet distribution, that is > down to the device sending packets e.g. your switch.. > yes, I know. but bnx(4) interfaces have master set differently, in contrast to em(4) interfaces. I'm really guessing, but maybe that clocking source has some effect for a switch.
