Avoid an unnecessary copy of a packet if it is already in a single mbuf.
Introduce an additional device flag for those NICs which require the
transmit buffers to be aligned to 32-bit boundaries.

(the equivalen fix for STABLE is slightly simpler because there are
no supported chips which require this alignment there.)
