CACHE: net: asix: Fix asix driver to work with data cache on
The asix driver did not align buffers, therefore it didn't work with data cache enabled. Fix this. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Joe Hershberger <joe.hershberger@gmail.com> Acked-by: Joe Hershberger <joe.hershberger@gmail.com>
