    ixl: enforce the assigned VF MAC address
    
    When allow-set-mac is disabled, the MAC filter validation condition
    rejects the assigned VF unicast address while allowing any different
    unicast address. The equality test was accidentally inverted when this
    code moved to the boolean address helper.
    
    Accept multicast and the assigned unicast address, and reject other
    unicast addresses as intended.
    
    Fixes:          7d4dceec1030 ("ixl(4): Fix VLAN HW filtering")
    
    (cherry picked from commit d2309d9d6dc6d5a9141314652d6c96ab46a9a62c)
