Hm, if "ip -d -s link" lists the state correctly, then it's most likely
a problem with libsocketcan. Anyway, for what purpose would you like to
use can_get_state()? It's not forseen for frequent polling of the CAN
error state. Please use error messages instead.

What Socket-CAN driver are you using for the IXXAT cards? There is still
no support in mainline Linux, IIRC. Maybe there is some mismatch with
the header files.
Hope it helps.
Wolfgang.
