## Field Documentation

### struct rte\_eth\_thresh tx\_thresh

Tx ring threshold registers.

Definition at line **1184** of file **rte\_ethdev.h**.

### uint16\_t tx\_rs\_thresh

Drives the setting of RS bit on TXDs.

Definition at line **1185** of file **rte\_ethdev.h**.

### uint16\_t tx\_free\_thresh

Start freeing Tx buffers if there are less free descriptors than this value.
