Fix up the Tx trailer length calculation. We can't believe the
trailer len from the xstate information because it was calculated
before the packet was put together and padding added. This bit
of code finds the padding value in the trailer, adds it to the
authentication length, and saves it so later we can put it into
the Tx descriptor to tell the device where to stop the checksum
calculation.

napi_alloc_skb() doesn't need to disable IRQs during the allocation,
and thus may save us a few cycles.
Doing so requires a small fix-up in the HiperTransport path, which
currently assumes a fixed NET_SKB_PAD headroom padding. napi_alloc_skb()
adds an additional NET_IP_ALIGN padding, so use the proper helper for
setting up the mac_header offset.
Use this opportunity to convert the non-NAPI path to netdev_alloc_skb(),
which means that skb->dev is now always set-up during allocation and
doesn't need to be assigned manually.
