syssrc/sys/dev/ic [netbsd-1-5]: i82557.c
Pull up rev. 1.36:
Since the RFA is allocated in a normal mbuf, as opposed to DMA-safe
memory that is explicitly mapped in a DMA-coherent manner, we must
make sure to PREREAD sync the RFA after noticing a clear "complete"
bit. Without this, the clear bit will linger in the cache, and the
CPU will not notice when the chip updates the bit via DMA later.
