编译内核时报错./include/net/sch_generic.h:535:28: error: inlining failed in call to always_inline 'qdisc_pkt_len': indirect function call with a yet undetermined callee static inline unsigned int qdisc_pkt_

直接修改头文件include/net/sch_generic.h中的qdisc_pkt_len函数

　　将static inline unsigned int qdisc_pkt_len修改为:

　　static unsigned int qdisc_pkt_len
