It uses CRC32 as a checksum and that cannot be offloaded to most commercial NICs. This will also have an impact on routers that manipulate the transport layer ports due to checksum recalculation cost (which is trivial for the checksum used in UDP and TCP)

Routers almost NEVER manipulate the transport unless they are doing something very un-Layer3 like NAT or some other encapsulation.
