STRUCT NET_DEVICE(9) | Network device support | STRUCT NET_DEVICE(9) |
NAME¶
struct_net_device - The DEVICE structure. Actually, this whole structure is a big mistake. It mixes I/O data with strictly “high-level” data, and it has to know about almost every data structure used in the INET module.
SYNOPSIS¶
struct net_device {
char name[IFNAMSIZ];
struct hlist_node name_hlist;
char * ifalias;
unsigned long mem_end;
unsigned long mem_start;
unsigned long base_addr;
int irq;
atomic_t carrier_changes;
unsigned long state;
struct list_head dev_list;
struct list_head napi_list;
struct list_head unreg_list;
struct list_head close_list;
struct list_head ptype_all;
struct list_head ptype_specific;
struct {unnamed_struct};
struct garp_port __rcu * garp_port;
struct mrp_port __rcu * mrp_port;
struct device dev;
const struct attribute_group * sysfs_groups[4];
const struct attribute_group * sysfs_rx_queue_group;
const struct rtnl_link_ops * rtnl_link_ops; #define GSO_MAX_SIZE 65536
unsigned int gso_max_size; #define GSO_MAX_SEGS 65535
u16 gso_max_segs; #ifdef CONFIG_DCB
const struct dcbnl_rtnl_ops * dcbnl_ops; #endif
u8 num_tc;
struct netdev_tc_txq tc_to_txq[TC_MAX_QUEUE]; #if IS_ENABLED(CONFIG_FCOE)
unsigned int fcoe_ddp_xid; #endif #if IS_ENABLED(CONFIG_CGROUP_NET_PRIO)
struct netprio_map __rcu * priomap; #endif
struct phy_device * phydev;
