/*
详细了解printk后，发现还有更简便的方法。

%p：打印裸指针(raw pointer)

%pF可打印函数指针的函数名和偏移地址

%pf只打印函数指针的函数名，不打印偏移地址。

如
printk("%pf",func[0]->action); 结果：
my_Set

%pM打印冒号分隔的MAC地址

%pm打印MAC地址的16进制无分隔

如
printk("%pM %pm\n", mac, mac) willprint:

2c:00:1d:00:1b:00 2c001d001b00

%I4打印无前导0的IPv4地址，%i4打印冒号分隔的IPv4地址
%I6打印无前导0的IPv6地址，%i6打印冒号分隔的IPv6地址
如
printk("%pI4 %pi4\n", ip, ip) will print:
127.0.0.1 127:0:0:1
