Hi,

in this code, pointer of local variable (mb_def) is returned by your changes.
mb_def should be static for each thread.

2014-10-22 19:55 GMT+09:00 Bruce Richardson <bruce.richardson@intel.com>:
> Remove the "static" prefix to the template mbuf variable in
> ixgbe_rxq_vec_setup function. This will then allow different
> threads to initialize different RX queues at the same time,
> without one overwriting the other's data.
