BTW I committed a change that disables IFEF_MPSAFE by default on
all interfaces because it seems that IFEF_MPSAFE requires additional

interface is guaranteed to be safe.
What additional changes?
For example, avoid updating if_flags (and reading it and depending on
the result) in Tx/Rx paths and using if_watchdog.

Ah, I see.

Do we have a model driver yet?

Thanks,
