[dpdk-dev] What is the max size of packets rte_eth_tx_burst() can send practically/theoritically?

Hello,


For example, as I understand,  ovs-dpdk code  uses a buffer of size 32
when it transmits via rte_eth_tx_burst().

I think it can transmit more packets in a bust.
I know there should be a balance between throughput and latency. But, I am
wondering what max size packets  a dpdk application can give  to
rte_eth_tx_burst()  practically/theoretically?
(I see some max macro in ixgbe_rxtx.h)

Thanks
