先看log打印：

[ 103.515484] dhd_get_memdump_info: File [/data/misc/wifi/.memdump.info] doesn't exist

在ap6212驱动添加完能正常使用后会有上面的log打印，可以看到“Firmware up: op_mode=0x0005, MAC=8c:f7:10:30:4a:20”这句打印，根据log打印可以找到获取mac地址的源码位置在drivers/net/wireless/rockchip_wlan/rkwifi/bcmdhd/dhd_linux.c中的dhd_preinit_ioctls，其实也尝试过在dhd_config.c中的dhd_conf_get_mac函数中去添加，但是添加后没有被调用到，所以就另辟蹊径，所以根据log提示去修改drivers/net/wireless/rockchip_wlan/rkwifi/bcmdhd/dhd_linux.c中的dhd_preinit_ioctls函数
int
dhd_preinit_ioctls(dhd_pub_t *dhd)
{
char mac[6]={
0x8c,0xf7,0x10,0x30,0x4a ,0x29}; //自己加的
...
/* Get the default device MAC address directly from firmware */
memset(buf, 0, sizeof(buf));
bcm_mkiovar("cur_etheraddr", 0, 0, buf, sizeof(buf));
if ((ret = dhd_wl_ioctl_cmd(dhd, WLC_GET_VAR, buf, sizeof(buf),
FALSE, 0)) < 0) {
DHD_ERROR(("%s: can't get MAC address , error=%d\n", __FUNCTION__, ret));
ret = BCME_NOTUP;
goto done;
}
/* Update public MAC address after reading from Firmware */
printk(" get_mac_src %X:%X:%X:%X:%X:%X\n",buf[0], buf[1],buf[2],buf[3],buf[4],buf[5]); //自己加的
memcpy(buf,mac, 6);
printk(" get_mac_mac %X:%X:%X:%X:%X:%X\n",buf[0], buf[1],buf[2],buf[3],buf[4],buf[5]); //自己加的
memcpy(dhd->mac.octet, buf, ETHER_ADDR_LEN);
...
DHD_ERROR(("Firmware up: op_mode=0x%04x, MAC="MACDBG"\n",
dhd->op_mode, MAC2STRDBG(dhd->mac.octet)));
#ifdef CUSTOMER_HW2
..
return ret;
}
成功后的log:
