If you can believe the OSA book, only OSE (LCS) chpids directly support 802.3 with 802.2 SNAP. I would expect layer 3 OSA connections on OSD chpids to discard the frames, as it supports only Ethernet II (DIX) and 802.3. In layer 2 mode, however, the frame is passed as-is (with SNAP headers) to the host. I don't know what the state of Linux's ethernet SNAP support is. The code in net/ethernet/eth.c that deals with (some of) this stuff looks a bit hazy to me. Dunno.
