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.

Thank you, that worked. I haven't read anything that mentioned adding

Mark,
try to move the "buffer_count" and "checksumming" line before the
"online" line. The qeth driver does not allow to change the buffer_count
value in online state.

How to change /udev/rules.d/ for hsi
Here's some more detail if that helps... The hipersocket address e000.
I've added the last 2 lines, 1 to increase the buffer cnt and the other to
turn off checksumming. Neither parameter changes during a reboot.
lsqeth -p still shows a cnt of 16 for the device

Is there something else that needs to be changed ? SLES 11
