[PATCH net-next 0/4] net: mvpp2: Add big-endian support

From: Maxime Chevallier
Date: Thu Jun 28 2018 - 08:42:53 EST


This series allows to use PPv2 on system built as big endian.

The first patch fixes the way we represent TX and RX descriptors, so that
they used fixed little endianness as expected by the PPv2 controller.

The second reworks the way we handle the software representation of the
Header Parser entries, so that we don't use a union of arrays.

The last two patches fixes some incorrect byte swapping logic, that wen't
un-noticed on little-endian.

This whole series doesn't fix any existing bug for little-endian systems, and
since big-endian never worked for this driver, I didn't include 'fixes' tags.

This was tested on MacchiatoBin (Armada 8040).
