To produce this problem: 1. modprobe ixgbe max_vfs=2 eth4 is PF, eth5 is VF 2. ip link set eth4 up 3. ip link add link eth4 address 54:52:00:35:e3:20 macvlan2 type macvlan 4. ip addr add 192.168.7.74/24 dev macvlan2 5. ping macvlan2 from remote host, works 6. ip link set eth5 up 7. ping macvlan2 from remote host failed.
Based on my understanding, the problem is: 1. PF set_rar use rar index is 0, and vmdq index is adapter->num_vfs, 2. when macvlan2 is created, rar index is based rar_used_count, which would be 1. 3. later when VF is up, the rar index is vf+1, and vmdq index is vf, so VF0 will overwrite macvlan2 rar entry. The fix here: 1. make sure PF uses vmdq index = adapter->num_vfs during initialization, reset. 2. reserve rar index for all VFs from 1 to num_vfs + 1. Please let me know whether my understanding is correct or not.
