Mr. Mark, Thank you for your reply. You exactly pointed out the mistake I had done with max_idle. I didn't initialized the mpsc_pdata structure in platform dependent file. Now I initialized max_idle =40. And every thing is working fine. Still facing some problems with mv64360 giga Ethernet driver. I will come back after a little bit of investigation.
