- **ethtool** operations on related kernel interfaces also affect the PMD.
+- ``rxq_cqe_comp_en`` parameter [int]
+
+ A nonzero value enables the compression of CQE on RX side. This feature
+ allows to save PCI bandwidth and improve performance at the cost of a
+ slightly higher CPU usage. Enabled by default.
+
+- ``txq_inline`` parameter [int]
+
+ Amount of data to be inlined during TX operations. Improves latency.
+ Can improve PPS performance when PCI back pressure is detected and may be
+ useful for scenarios involving heavy traffic on many queues.
+
+ It is not enabled by default (set to 0) since the additional software
+ logic necessary to handle this mode can lower performance when back
+ pressure is not expected.
+
+- ``txqs_min_inline`` parameter [int]
+
+ Enable inline send only when the number of TX queues is greater or equal
+ to this value.
+
+ This option should be used in combination with ``txq_inline`` above.
+
+- ``txq_mpw_en`` parameter [int]
+
+ A nonzero value enables multi-packet send. This feature allows the TX
+ burst function to pack up to five packets in two descriptors in order to
+ save PCI bandwidth and improve performance at the cost of a slightly
+ higher CPU usage.
+
+ It is currently only supported on the ConnectX-4 Lx family of adapters.
+ Enabled by default.
