Hi,

I am trying to establish a uni-directional Ethernet link where a singular fiber is used to transmit data to the receiver in the DPDK environment. The Rx of the transmit side and the Tx of the receive side are not physically connected, like in a Data diode scenario. The ethernet controller on both sides is intel 82580.

my problem is that when I detach the RX line from one side, both sides' links go down.

Could anyone please give me some advice to solve this problem and establish a valid unidirectional ethernet link?
