I am using two DELL Poweredge R430 servers and each server has one dual port XL710-QDA2 . Now we want to connect these two NICs directly using XLDACBL3  cable, but we are not sure if the setup will work. On server 1, we are running DPDK based L2Fwd application and on the other server DPDK-pktgen is generating the packets. Server 1 returns the packets back to server 2.
So can we use XLDACBL3 cables to connect these NICs directly and will they work in full-duplex mode?
