I agree with you that it's not necessary for Ethernet/IP traffic. The
point is that this isn't really Ethernet/IP traffic, it's InfiniBand/IP
traffic. And there it *is* necessary. An argument can be made that the
core code shouldn't assume Ethernet/IP and should support either
Ethernet/IP or InfiniBand/IP.
