Re: [PATCH net-next v7 3/7] r8169: add support for phylink

+	if (jumbo_before != jumbo_after) {
+		unsigned long caps = tp->phylink_config.mac_capabilities;
+
+		if (jumbo_after)
+			caps &= ~(MAC_SYM_PAUSE | MAC_ASYM_PAUSE);
+		else
+			caps |= (MAC_SYM_PAUSE | MAC_ASYM_PAUSE);
+
+		phylink_update_mac_pause_capabilities(tp->phylink, caps);

The name suggests it only changes pause. So i would expect the caps
parameter passed here to only cover MAC_SYM_PAUSE & MAC_ASYM_PAUSE. So
i don't see a need to look at tp->phylink_config.mac_capabilities.
