dm9000c 移值新内核 linux-4.1.24
错误 1
/home/dm9000/dm9dev9000c.c:309: error: conflicting types for 'phy_read'
include/linux/phy.h:637: error: previous definition of 'phy_read' was here
/home/dm9000/dm9dev9000c.c:310: error: conflicting types for 'phy_write'
include/linux/phy.h:652: error: previous definition of 'phy_write' was here
linux/phy.h 也定义了这个函数，所以这里要改名.
phy_read 改名为 dm9000_phy_read
错误 2
dm9dev9000c.c:356: error: implicit declaration of function 'SET_MODULE_OWNER'
查看 linux2.6.22 源码查看发现只是一个宏定义 #define SET_MODULE_OWNER(dev) do { } while (0)
错误 3
/home/dm9000/dm9dev9000c.c:407: error: 'struct net_device' has no member named 'priv'
/home/dm9000/dm9dev9000c.c:408: error: 'struct net_device' has no member named 'priv'
/home/dm9000/dm9dev9000c.c:422: error: 'struct net_device' has no member named 'open'
/home/dm9000/dm9dev9000c.c:423: error: 'struct net_device' has no member named 'hard_start_xmit'
/* Allocated board information structure */
memset(dev->priv, 0, sizeof(struct board_info));
db = (board_info_t *)dev->priv;
改为
db = netdev_priv(dev);
/* Allocated board information structure */
memset(db, 0, sizeof(struct board_info));
这里改的比较多，最后见补丁吧
static const struct net_device_ops dm9000_netdev_ops = {

需要复制 内核自带的 dm9000.h
