Subject: [PATCH net 0/3] dpaa2-eth: software TSO fixes

This patch fixes the software TSO feature in dpaa2-eth.

There are multiple errors that I made in the initial submission of the
code, which I didn't caught since I was always running with passthough
IOMMU.

The bug report came in bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=215886

The bugs are in the Tx confirmation path, where I was trying to retrieve
a virtual address after DMA unmapping the area. Besides that, another
dma_unmap call was made with the wrong size.

Ioana Ciornei (3):
  dpaa2-eth: retrieve the virtual address before dma_unmap
  dpaa2-eth: use the correct software annotation field
  dpaa2-eth: unmap the SGT buffer before accessing its contents
