It seems oldlink could be bool as well.

drivers/net/ethernet/stmicro/stmmac/stmmac.h:   int oldlink;
drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:              if (!priv->oldlink) {
drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:                      priv->oldlink = 1;
drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:      } else if (priv->oldlink) {
drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:              priv->oldlink = 0;
drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:      priv->oldlink = 0;
drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:      priv->oldlink = 0;
