Merge branch 'dpaa_eth-buffer-layout-fixes'
Camelia Groza says:
====================
dpaa_eth: buffer layout fixes
The patches are related to the software workaround for the A050385 erratum.
The first patch ensures optimal buffer usage for non-erratum scenarios. The
second patch fixes a currently inconsequential discrepancy between the
FMan and Ethernet drivers.
Changes in v3:
- refactor defines for clarity in 1/2
- add more details on the user impact in 1/2
- remove unnecessary inline identifier in 2/2
Changes in v2:
- make the returned value for TX ports explicit in 2/2
- simplify the buf_layout reference in 2/2
