Therefore the only reason we store an entire flow inside of the

Rewrite ip_route_newports() such that:

made:

1) The counter of the number of messages sent by a port now starts
   at zero, rather than one. This prevents the port from reporting port
   congestion one message earlier than it was supposed to.

2) The counter of the number of messages sent by a port is now
   incremented only if a non-empty message is sent successfully.
   This prevents the port from becoming permanently congested if
   too many send attempts are unsuccessful because of congestion
   (or other reasons). It also removes the risk that empty hand-
   shaking messages used during connection setup might cause the
   port to report congestion earlier than it was supposed to.

3) The counter of the number of unacknowledged messages received by
   a port controlled by an internal TIPC service is now incremented
   only if the message is non-empty, in order to be consistent with

13 years agor6040: fix multicast operations
Shawn Lin [Wed, 23 Feb 2011 04:32:34 +0000 (04:32 +0000)]
r6040: fix multicast operations

The original code does not work well when the number of mulitcast
address to handle is greater than MCAST_MAX. It only enable promiscous
mode instead of multicast hash table mode, so the hash table function
will not be activated and all multicast frames will be recieved in this
condition.

This patch fixes the following issues with the r6040 NIC operating in
multicast:

1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC
hash table registers to make it process multicast traffic.

2) When the number of multicast address to handle is smaller than
MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}.

3) The hashing of the address was not correct, due to an invalid
substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an
incorrect crc algorithm (ether_crc_le) instead of (ether_crc).

4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast
hash table function.
