Re: [dpdk-users] [dpdk-dev] I40e-dpdk_18.11-Bonding issue

Hi, Nishant,
	according to the log, it failed when VF called 
rte_eth_dev_default_mac_addr_set. I think it may has nothing
to do with bond. I suggest you check out the ops (i40e driver)
,that is, 'i40evf_set_default_mac_addr', maybe check out the input
parameter, or the communication way between VF and PF, to figure out
if they exist any bugs.
	Thanks.
