During interface toggle operations (ifdown/ifup), the driver currently
resets the local helper variable 'phy_link' to -1. This causes the link
state machine to incorrectly interpret the state as a link change event,
resulting in spurious "Link is down" messages being logged when the
interface is brought back up.
Preserve the phy_link state across interface toggles to avoid treating
the -1 sentinel value as a legitimate link state transition.
