Great! However, it does not quite work for me (on -current as of
yesterday, with version 1.36 of if_bfe.c). Busdma wants a lock
function:
panic: driver error: busdma dflt_lock called
Using busdma_lock_mutex() and &sc->bfe_mtx results in watchdog
timeouts, lots of LORs and no network traffic, so some other lock is
apparently needed.
Any ideas?
