Also, if you are going to increase MAX_QUEUES, shouldn't you increase the NUM_MBUFS_PER_PORT? Looking at the comment below, looks like there is a calculation of number of mbufs based on number of queues. Plus, I assume 128 is the maximum number of queues per port, and as far as I know, only Fortville supports 256 as maximum. Thanks, Pablo ^ permalink raw reply [flat|nested] 10+ messages in thread

And as you say, NUM_MBUFS_PER_PORT should be increased actually. I may use macro to replace the old expression. #define NUM_MBUFS_PER_PORT (MAX_QUEUES * max(RTE_TEST_RX_DESC_DEFAULT,RTE_TEST_TX_DESC_DEFAULT)) And this patch is to fix the issue about running VMDQ on Fortville, so the maximum number of queues is larger than 128.
