+==== TRex specific implementation details 
 
 TRex uses flow director filter to steer specific packets to specific queues. 
 To support that we change IPv4.TOS/Ipv6.TC  LSB to *1* to be steered. So latency packets will have this bit turn on (not only for ConnectX-4)
+Watch out, In case DUT will clear this bit (change the TOS with LSB==0, e.g. 0x3->0x2) packets won't be forward to TRex.
 
+==== Which NIC to buy?
+
+NIC with two ports will work better from performance prospective, so it is better to have MCX455A-ECAT(two 100gb port) and *not* the  MCX456A-ECAT (one 100gb port).
