This patch removes the MCAM preallocation scheme. The free
entry cache is removed and for every flow created, an MCAM
allocation request is made to the kernel. Each priority level
has a list of MCAM entries. For every flow rule added, the
MCAM entry obtained from kernel is checked if it is at the
correct user specified priority. If not, the existing rules
are moved across MCAM entries so that the user specified
priority is maintained.
