The packet is completed with NDIS_BUFFER_TOO_SHORT error.
__send_mgr_filter_ip unwinds to __send_mgr_filter which unwinds to
__build_send_desc which unwinds to ipoib_port_send, where the status
is checked and the packet is discarded.

Yes, this is the assumption.  In my testing, I have never seen it
otherwise.  The first buffer, if it doesn't contain the IP header,
contains just the Ethernet header.
