Hi,
i tried setting the mtu on one of my ixgbe(4) intel NICs to support
jumbo frames. This is on a box with RELENG_8 from today.
# ifconfig ix0 mtu 9198
I then get the following error:
# tail -n 1 /var/log/messages
Apr 14 12:48:43 siloneu kernel: ix0: Could not setup receive structures
I already tried the following patch because of Jack Vogel's advice given
in the following thread on -stable in Oct. last year, which still
produces the same error message and leaves the box unpingable:

If you get this message its only for one reason, you don't have enough mbufs to fill your rings. You must do one of two things, either reduce the number of queues, or increase the relevant mbuf pool. Increase the 9K mbuf cluster pool.
