Solution
ARINC 825 and other protocol specifications are not supported the XNET driver even though they are built on the CAN standard. NI-XNET supports these different protocols until the Transport Layer (everything below the transport layer in the following image). ARINC-825 and other protocols based on CAN fall above the CAN Transport Layer. It may be possible to read/write the ARINC 825 messages as normal CAN frames, but you would have to implement the rest of the protocol yourself in your application.
