+ Specifies the Tx steering mode for the interface. +

+

+ thread enables static (1:1) thread-to-txq mapping when + the number of Tx queues is greater than number of PMD threads, and + dynamic (N:1) mapping if equal or lower. In this mode a single thread + can not use more than 1 transmit queue of a given port. +

+

+ hash enables hash-based Tx steering, which distributes + the packets on all the transmit queues based on their 5-tuples + hashes. +

+

+ Defaults to thread. +
