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.
