[이문복]

Hello~~^^

I was developed to sdk 3.1 in ixp2400.
Um...

I buy ixp2400/ixp2800 Programming on Amazon.
MSF device is SPI4 in ixp2800 but ixp2400 is POS-PHY Level 3.

What kind of difference ixp2800 and ixp2400? 

I hold only one of scratch ring for single PHY.
Therefore, scatch ring size hold 1024. 
Right ? ...

...
MSF_interrupt_status = 0x0000 0e00

May be, no rbuf element was free to accept mpacket.

Please, solve me~~!

Thanks in advance.
