If we replcase only ARRAY_SIZE then cood will look alike to drivers/net/ethernet/intel/e1000e/phy.c And if we have to remove these #defines , then we can also remove it from drivers/net/ethernet/intel/e1000e/phy.c Because same operations and same usage is there in both files. what say? >> diff --git a/drivers/net/ethernet/intel/igb/e1000_phy.c b/drivers/net/ethernet/intel/igb/e1000_phy.c >[] >> @@ -37,8 +37,7 @@ static s32 igb_set_master_slave_mode(struct e1000_hw *hw); >> static const u16 e1000_m88_cable_length_table[] = { >> 0, 50, 80, 110, 140, 140, E1000_CABLE_LENGTH_UNDEFINED }; >> #define M88E1000_CABLE_LENGTH_TABLE_SIZE \ >> - (sizeof(e1000_m88_cable_length_table) / \ >> - sizeof(e1000_m88_cable_length_table[0])) >> + ARRAY_SIZE(e1000_m88_cable_length_table) >>
