Bestcomm trouble with NAPI for MPC5200 FEC

2009-07-09 Thread Wolfgang Grandegger
Hello, I'm currently trying to implement NAPI for the FEC on the MPC5200 to solve the well known problem, that network packet storms can cause interrupt flooding, which may totally block the system. The NAPI implementation, in principle, is straight forward and works well under normal and moderate
