Hi, I'm running an ixgbevf PMD on an AWS guests with extended networking (SR-IOV functions of 82599 Intel's NIC) and noticed that even in the current git tree there is no support for a multi-queue in this PMD: reta size returned by rte_eth_dev_info_get() call is 0, while max_rx_queues and max_tx_queues are both 4.
Linux ixgbevf-2.15.3 driver on the other hand successfully initializes 2 RSS queues: for some reason it always limits the number of RSS queues by 2. ixgbevf_main.c: line 2539 u16 rss = min_t(u16, num_online_cpus(), 2); The above is strange since if MRQE is set to 1010b there are 4 RSS queues available which seems to be the case in my AWS Guest. However, let's get back to DPDK. As I've mentioned above the SR-IOV function i have is RSS capable (to be 100% sure I've verified both queues are receiving packets in a multi-socket TCP test). And it's a shame I can't utilize it with a DPDK. I wonder if there are any blockers to add this capability to the ixgbevf PMD and if not is it scheduled to some time soon? Thanks in advance, vlad
