Add feature bit to existing device caps field. EFA supports data polling of 128 bytes blocks. The flag indicates that the NIC guarentees that a 128 byte aligned block is written in order, ie that observing the last 8 bits of the block mean the prior 127 bytes are also written. It is useful for "last data polling" acceleration techniques.
