By registering the HDLC device to the uClinux kernel as an Ethernet device and carrying out protocol conversion between Ethernet and HDLC in the device driver,high efficient data forwarding between Ethernet and HDLC interface is achieved.

• 采取将HDLC接口向内核注册为Ethernet设备,并在驱动中完成Ethernet与HDLC协议间转换的设计方案,实现了数据在Ethernet和HDLC接口间的高效转发。
