SVN rev 200571 on 2009-12-15 10:36:08Z by stas
- MFC r198318:
- On entrance to the rx_eof sync RX rings maps with POSTWRITE flag
instead of POSTREAD: the hardware do not touch this memory (CPU
updates it). It is already synchronized as PREWRITE after the
processing is done.
- Synchronize RX return ring memory in rx_eof. This is needed
as the deviced updates this memory when receives packets.
- Decouple the synchronization of BGE status block in the interrupt
service routine: perfrom PREREAD synchronization only all accesses
to this block are finished. This seems to be more natural.
