SVN rev 212324 on 2010-09-08 17:11:49Z by jchandra
nlge (alternate XLR GMAC driver) updates:
- Updates for the message ring clean up in r212321.
- Instead of dropping Tx packet on credit fail, retry send until it
succeeds.
- Fix freeing mbufs in case of P2P descriptors:
We cannot free the mbuf when the P2P descriptor freeback is received. The
mbuf may be still in use by the GMAC, since the P2P freeback indicates that
it read the P2D descriptors in the P2P message.
Now we free just the P2P descriptor when the P2P freeback message is
received. Another freeback P2D message has been added to the end of
the packet descriptors, the mbuf will be freed only when we received
this.
The P2P descriptor issue was reported by srgorti at netlogicmicro dot com.
