Why size upto mac_addr is 9 and is not divisible by 2 is it?
or the mac_addr size is 6 which is divisible by 2 (__align(2))
this is full pahole:
struct eeprom_priv {
u8 bautoload_fail_flag; /* 0 1 */
u8 bempty; /* 1 1 */
u8 sys_config; /* 2 1 */
u8 mac_addr[6]; /* 3 6 */
u8 config0; /* 9 1 */
u16 channel_plan; /* 10 2 */
u8 country_string[3]; /* 12 3 */
u8 tx_power_b[15]; /* 15 15 */
u8 tx_power_g[15]; /* 30 15 */
u8 tx_power_a[201]; /* 45 201 */
/* --- cacheline 3 boundary (192 bytes) was 54 bytes ago --- */
u8 efuse_eeprom_data[256]; /* 246 256 */
/* XXX 2 bytes hole, try to pack */
/* --- cacheline 7 boundary (448 bytes) was 56 bytes ago --- */
enum RT_CUSTOMER_ID CustomerID; /* 504 4 */
/* size: 508, cachelines: 8, members: 12 */
/* sum members: 506, holes: 1, sum holes: 2 */
/* last cacheline: 60 bytes */
};
thanks!
