I don't know if this is from same person/team, but if not please check
following mail thread for same issue:
http://dpdk.org/ml/archives/dev/2016-June/042323.html
If issue is still valid for you:
Briefly, weak function is defined for the case RTE_IXGBE_INC_VECTOR
config option not enabled.
Which one to link against will be chosen on build time, if app linked
against first one, I would guess RTE_IXGBE_INC_VECTOR is not enabled,
can you please share the output of:
objdump -x librte_pmd_i40e.a| grep i40e_rx_vec_dev_conf_condition_check
Thanks,
ferruh
