netif_dbg 有的會印, 有的不會印

 netif_dbg

netif_dbg(pdata, drv, pdata->netdev, "???!!!\n");  不會印

netif_dbg(pdata, link, pdata->netdev, "CL73 AN initialized hahaha ~~~\n");  會印

#define netif_dbg(priv, type, netdev, format, args...) \

do { \

if (netif_msg_##type(priv)) \

dynamic_netdev_dbg(netdev, format, ##args); \

} while (0)

#define netif_msg_drv(p) ((p)->msg_enable & NETIF_MSG_DRV)

#define netif_msg_probe(p) ((p)->msg_enable & NETIF_MSG_PROBE)

#define netif_msg_link(p) ((p)->msg_enable & NETIF_MSG_LINK)

可以看的出來是priv的變數中決定哪一些要印的.

請以NETIF_MSG_LINK之類作為關鍵字搜尋, 把自己想印的加進去
