[PATCH 02/30] rapidio/rionet: add capability to change MTU

From: Aurelien Jacquiot Replace default Ethernet-specific routine by the custom one to allow setting of larger MTU supported by RapidIO messaging (max RIO packet size is 4096 bytes). Signed-off-by: Aurelien Jacquiot Signed-off-by: Alexandre Bounine Cc: Matt Porter Cc: Andre van Herk Cc

[PATCH 11/30] rapidio/rionet: add shutdown event handling

Add shutdown notification handler which terminates active connections with remote RapidIO nodes. This prevents remote nodes from sending packets to the powered off node and eliminates hardware error events on remote nodes. Signed-off-by: Alexandre Bounine Cc: Matt Porter Cc: Aurelien Jacquiot
