net: stmmac: RX buffer size must be 16 byte aligned
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") Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S.
