  On four-port wm cards, there is some sort of pci-pci bridge (to two
  dual wm chips), and netbsd-5 and netbsd-6 both (as of early 2012) fail
  to cope, causing some sort of inscrutable hard lockup.  This is not
  about having 4 wm interfaces; it's specifically about the quad-port
  PCI-E cards with a PCI-PCI bridge and 2 chips, each of which is a
  2-function PCI device.

  In if_bnx.c, there is incorrect handling of failure to get a
  related to multiple interfaces, but can be more likely triggered since
  allocates 510 cluster mbufs per interface, even with no traffic,
  problem; we've been pushing multiple-interface machines pretty hard.
