net: stmmac: RX buffer size must be 16 byte aligned
[ Upstream commit 8d558f0294fe92e04af192e221d0d0f6a180ee7b ]
We need to align the RX buffer size to at least 16 byte so that IP
doesn't mis-behave. This is required by HW.
Changes from v2:
- Align UP and not DOWN (David)
Fixes: 7ac6653a085b ("stmmac: Move the STMicroelectronics driver")
