I've got almost the same problem with intel 82574L based nic. My
platform is nvidia ion running Atom 1.6 and nic is an external
PCI-express adapter. Unlike Jason's case mine is always stuck in
receiving traffic, it's Ierrs increasing while Ipkts not. Thanks to
Jason's script I can see those locks and interface flapping every
several hours. My system is not a heavy loaded server but just a home
nas/router, usually routing at 100 mbps or less. Nither disabling
MSIX nor tuning txd rxd doesn't help me.
