Subject: [PATCH can-next v8 01/17] can: dev: can_get_ctrlmode_str: use
 capitalized ctrlmode strings

From: Oliver Hartkopp <socketcan@...tkopp.net>

Unify the ctrlmode related strings to the command line options of the
'ip' tool from the iproute2 package. The capitalized strings are also
shown when the detailed interface configuration is printed by 'ip'.
