[c-nsp] Me3600 microburst / drops / queue-limit

[Xu Hu]

I remember last time I also encounter such issue caused by microburst, we change the input q size to 2000 from default 70.
And also I remember we can check the buffer loss is how many packets through show buffer command.

Thanks and regards,
Xu Hu
