[ Upstream commit 645603844270b69175899268be68b871295764fe ]
After reinitialization of iavf, ice driver gets VIRTCHNL_OP_ADD_ETH_ADDR
message with incorrectly set type of MAC address. Hardware address should
have is_primary flag set as true. This way ice driver knows what it has
to set as a MAC address.
Check if the address is primary in iavf_add_filter function and set flag
accordingly.
To test set all-zero MAC on a VF. This triggers iavf re-initialization
and VIRTCHNL_OP_ADD_ETH_ADDR message gets sent to PF.
For example:
ip link set dev ens785 vf 0 mac 00:00:00:00:00:00
This triggers re-initialization of iavf. New MAC should be assigned.
Now check if MAC is non-zero:
ip link show dev ens785
Fixes: a3e839d539e0 ("iavf: Add usage of new virtchnl format to set default MAC")
