if_rue.c if_udav.c
Log:
Mark USB ethernet devices as IFF_NEEDSGIANT, since the USB framework
if_start routines cannot currently be entered without Giant. When
the kernel is running with debug.mpsafenet != 0, this will defer
if_start execution to a task queue thread holding Giant, which may
introduce additional latency, but avoid incorrect execution.
