=======================Test Group Band Edge Power========================
上面的数据是读取驱动的数据而来;其代码为:
ar9300EepromDumpSupport(struct ath_hal *ah, void **ppE)
{
printk("ar9300EepromDumpSupport \n");
*ppE = &(AH9300(ah)->ah_eeprom);
return sizeof(ar9300_eeprom_t);
}
上面的可以知道,获取的是结构体

其中这个&(AH9300(ah)->ah_eeprom 地址的值是怎么来的了,这里要加一个打印信息来看看代码的执行流程,目前有一点可以确认的是,WiFi的MAC地址的值来自于上面的macAddr 这个字段。
2:分区数据格式
有上面的可以知道,在此分区的最前面的字节可以用来定义MAC地址,为Atheros Ethernet的MAC地址。在其代码
默认的MAC地址从地址:CONFIG_ATHR_GMAC_LOCATION 处来进行获取,CONFIG_ATHR_GMAC_LOCATION的定义如下:
#define CONFIG_AG7240_MAC_LOCATION 0xbfff0000
