Hmm.. no problem... unless you think about the other macro?

pkt_sched: sch_htb: Clean L2T()

L2T() is currently used only in one place, so let's move it closer to
this place, remove unused cl parameter.

You misunderstood me.

I meant get rid of L2T completely, and just use
"qdisc_l2t(rate, size)" directly.

Macros like this one:

1) are used in only one spot
2) give no new information to the reader

so are just extra noise.
