+``ETHTOOL_A_RINGS_CQE_SIZE`` specifies the completion queue event size.
+Completion queue events(CQE) are the events posted by NIC to indicate the
+completion status of a packet when the packet is sent(like send success or
+error) or received(like pointers to packet fragments). The CQE size parameter
+enables to modify the CQE size other than default size if NIC supports it.
+A bigger CQE can have more receive buffer pointers inturn NIC can transfer
+a bigger frame from wire. Based on the NIC hardware, the overall completion
+queue size can be adjusted in the driver if CQE size is modified.
