大纲/内容

virtual void SetIfIndex (const uint32_t index) = 0;
virtual uint32_t GetIfIndex (void) const = 0;

virtual Ptr<Channel> GetChannel (void) const = 0;
return the channel this NetDevice is connected to. The value
returned can be zero if the NetDevice is not yet connecte

virtual void SetAddress (Address address) = 0;
virtual Address GetAddress (void) const = 0;
Set the address of this interface

virtual bool SetMtu (const uint16_t mtu) = 0;
virtual uint16_t GetMtu (void) const = 0;
Override for default MTU defined on a per-type basis.
根据每种类型定义最大传输单元

virtual bool IsLinkUp (void) const = 0;
return true if link is up; false otherwise

这里有一系列判断是否广播，单播和桥接等

virtual bool Send (Ptr<Packet> packet, const Address& dest, uint16_t protocolNumber) = 0;
Called from higher layer to send packet into Network Deviceto the specified destination Address

virtual bool SendFrom (Ptr<Packet> packet, const Address& source, const Address& dest, uint16_t protocolNumber) = 0;
Called from higher layer to send packet into Network Devicewith the specified source and destination Addresses.

virtual Ptr<Node> GetNode (void) const = 0;
virtual void SetNode (Ptr<Node> node) = 0;
returns the node base class which contains this networkinterface.
