Clearing of one Descriptor list with out affecting the transmission of another Descriptor list


I'm working on a project where two descriptor lists are used ie., two separate queue(q0 and q1).HW is configured in SGMII mode and running on 1Gbps speed. And the question is based on the GEM peripheral for Ethernet communication.

Both the queues are used for transmission.

How can I clear only one descriptor list? With out affecting the transmission of another list?
Because we cannot modify the values of Descriptor unless we stop the transmission. And doing this will stop the transmission of both the queues. 
Is there any other way to achieve this ?
