compile probs with LEDE

[thuehn]

Hi,

Current sched_fq_pie does not compile under LEDE when selected in make menuconfig.
It looks like the proper header file for function qdisc_tree_decrease_qlen() is missing (defined in sch_generic.h but not included). I am not quite sure where to add it properly.

Greetings Thomas

While fq_pie is "interesting", active development on it has ceased. It is also different from the fq_pie that just entered BSD. I like a few of the ideas in this module, and would have liked to have kept it working for further evaluation. I will ping the author.
