IPoIB: Handle 4K IB MTU for UD (datagram) mode
This patch enables IPoIB to use 4K UD messages (when the underlying device and fabrics support a 4K MTU) by using two scatter buffers when PAGE_SIZE is less than or equal to thhe HCA IB MTU size. The first buffer is for IPoIB header + GRH header, and the second buffer is the IPoIB payload, which is 4K-4.
