[dpdk-dev] Sending and receiving on the same port at the same time, from different threads

[Zoltan Kiss]

Hi,

I've been asked this question, and I realized I'm not sure about the 
answer. In other words: can you call rte_eth_tx_burst() and 
rte_eth_tx_burst() on the same port at the same time from different 
threads? In theory it seems possible, as you still access different 
queues (an RX and a TX one), and at least taking a glance at ixgbe 
vector functions, they don't seem to use common resources while doing RX 
or TX. But I'm not sure that it's generally true, although I always 
assumed that it should be true. Have anyone seen a device where it 
wasn't true?

Regards,

Zoltan
