Oliver Hartkopp 323a391a22 can: isotp: isotp_setsockopt(): block setsockopt on bound sockets ... The isotp socket can be widely configured in its behaviour regarding addressing types, fill-ups, receive pattern tests and link layer length. Usually all these settings need to be fixed before bind() and can not be changed afterwards. This patch adds a check to enforce the common usage pattern.
