Subject: [PATCH iproute2-next v3 2/7] iplink_can: print_usage: change unit
 for minimum time quanta to mtq

In the vast majority of the available CAN datasheets, the minimum time
quanta is abbreviated as "mtq". Note that the ISO standard uses "tqmin"
(with the "min" part as a subscript).

One fact is that no one seems to be using "tc". I was actually the one who
initially proposed to use "tc", but I can not recall anymore the reasoning
behind that.

Change the minimum time quanta unit from "tc" to "mtq" to follow what the
majority of the industry does.
