net: stmmac: xgmac: Fix AV Feature detection
Fix incorrect precedence of operators. For reference: AV implies AV Feature but RAV implies only RX side AV Feature. As we want full AV features we need to check RAV. Fixes: c2b69474d63b ("net: stmmac: xgmac: Correct RAVSEL field interpretation") Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
