Due to alignment requirements of the hardware transmissions are split
into two DMA requests,
Rather DMA descriptors.
a small padding request of 0 - 4 bytes in length

Due to alignment requirements of the hardware transmissions are split
into two DMA requests, a small padding request of 0 - 4 bytes in length
followed by the a request for rest of the packet.
In the case of IP packets the first request will never be zero due
to the way that th
