Starterware AM335x Ethernet(CPSW) Subsystem

Dear Team,

                    I am Working on a project which mainly concerns about the Ethernet.I am in a position to understand the Porting of LWIP in AM335x of starter ware . I have few queries regarding the CPPI DMA Channel Allocation and Porting.

1.In starter ware (cpswif.c) indicates that supports only Channel 0,Is there any limitation to use other channels?

2.If we use the Other channels( 0 - 7 ),It will increase the throughput or Not?

3.How CPPI DMA Will behave,If all channels are active? 

4.In tx handler(cpswif.c) after EOI,Why again allocating the rx_buffers for receiving(They are  allocating after serving the Rx interrupt )?

5.Is there any Known bugs while using of LWIP1.4.0 in AM335x?

I am using AM335x GPEVM and EVMSK for development purpose.

Thanks & Regards

Rama Krishna
