Print an informational message in iavf_mac_add_ok() when the PF confirms the primary MAC filter. This gives operators a clear confirmation of the active MAC address in dmesg. Save the confirmed address to a local variable and emit the log after releasing mac_vlan_list_lock to avoid holding a spinlock across printk. Print f->macaddr directly rather than adapter->hw.mac.addr: the filter address is the value the PF actually accepted and is protected by the held lock, while hw.mac.addr is not.
