dear all

i want to use both of the phy port on the DE2-115 board.

In Qsys i add one tse mac (select 4 port), 2 sgdma_rx, 2 sgdma_tx and 2 descriptor_mem based on the example "DE2_115_WEB_SERVER_MII_ENET0".

then i build software in eclipse with the temple of "simple socket server" .

but i do not know how to operation sgdma_rx_1 and sgdma_tx_1?

i just want to add them as the buffer of the second port.

thx!
