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. Th= e Rx of the transmit side and the Tx of the=20 receive side are not physically connected, like in a Data diode=20 scenario. The ethernet controller on both sides is intel 82580.
<= /p>

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 probl= em and establish a valid unidirectional ethernet link?
