Merge branch 'ionic-tx-updates'

Shannon Nelson says:

====================
ionic Tx updates

Just as the Rx path recently got a face lift, it is time for the Tx path to
get some attention.  The original TSO-to-descriptor mapping was ugly and
convoluted and needed some deep work.  This series pulls the dma mapping
out of the descriptor frag mapping loop and makes the dma mapping more
generic for use in the non-TSO case.
