Re: [dpdk-dev] Does the rte_eth_tx_burst() function is multi-threaded safe when sending pkt in same port and same queue ?

[Stephen Hemminger <stephen@networkplumber.org>]

The rx and tx functions are safe only if a queue is not shared by
multiple threads (or the threads synchronize through some other
mechanism). The safest design is to only use a queue on a single core.
You will see different architectures in the examples. Some use one
queue per core, and others use separate receive and transmit cores.
