Not very understand why only vf->mac_addr can be moved?
It it checks if the mac address we want to delete, similar to the function
rte_pmd_i40e_set_vf_mac_addr where we set the mac address of a VF.
But in this way, seems we can't delete the mac address added by
rte_pmd_i40e_add_vf_mac_addr.
set_vf_mac_addr should be used for setting default mac address, right?
OK, I understand what you mean.
I have fixed it now. We reset the vf->mac_addr only if the mac address
is matched.
Then we delete it from the vsi->mac_list.
Thanks,
Awal.
I think any mac address in vsi->mac_list can be removed.
Yes, it is removed from the vsi->mac_list in the next line if the mac address is
matched in the previous checking.

Here we reset the mac address of a VF with null address, reverting the
operation of function rte_pmd_i40e_set_vf_mac_addr where we set the
mac address of a VF.

+ i40e_vsi_delete_mac(vsi, mac_addr);
