[ upstream commit d81cea5280112f5f6c8796c2fb0bad72bf29d41e ]
Preallocation of MCAM entries is not valid anymore since the
AF side MCAM allocation scheme has changed. This patch disables
preallocation by changing the default MCAM preallocation size
from 8 to 1.
Fixes: 168c59cfe42 ("net/octeontx2: add flow MCAM utility functions")
Signed-off-by: Satheesh Paul <psatheesh@marvell.com>
