Hello, 2011/4/27 Jack Vogel <jfvogel@gmail.com>: > If you get "cannot setup receive structures" you cannot go on and try to > use the thing :) It means you have inadequate mbuf clusters to setup > your receive side, you simply have to increase it and reload the driver. I tried increasing kern.ipc.nmbjumbo* (is it what you suggested ?). Values doubled : kern.ipc.nmbjumbo16: 6400 kern.ipc.nmbjumbo9: 12800 kern.ipc.nmbjumbop: 25600 And unloaded / reloaded the kernel module. Still no luck, same problem, on latest 9-CURRENT (r221363). %sysctl -a | grep mbuf dev.em.0.mbuf_alloc_fail: 0 What can I do ? Do you want a dump of "sysctl dev.em" with old and new if_em module ?
