[PATCH v3 02/14] can: janz-ican3: add software tx timestamp

[Vincent Mailhol <mailhol.vincent@wanadoo.fr>]

TX timestamps were added to the can_put_echo_skb() function of can_dev
modules in [1]. However, janz-ican3 does not rely on that function but
instead implements its own echo_skb logic. As such it does not offer
TX timestamping.

Add a call to skb_tx_timestamp() in the ican3_put_echo_skb() function
so that the module now supports TX software timestamps.

tx timestamps")
