- * **CONFIG_RTE_LIBRTE_ARK_PAD_TX** (default y): When enabled TX
- packets are padded to 60 bytes to support downstream MACS.
+ * **RTE_LIBRTE_ARK_MIN_TX_PKTLEN** (default 0): Sets the minimum
+ packet length for tx packets to the FPGA. Packets less than this
+ length are padded to meet the requirement. This allows padding to
+ be offloaded or remain in host software.
