fib: allow vnet rewrite max size to be smaller the pre_data
There is no reason to enforce vnet rewrite size to be equal to pre_data. Moreover, since vnet rewrite size is now saved as u8, this limits pre_data to 192 bytes. Type: fix Fixes: 7dbf9a1a4fff5c3b20ad972289e49e3f88e82f2d Change-Id: I3f848aa905ea4a794f3b4aa62c929a481261a3f1 Signed-off-by: Benoît Ganne <bganne@cisco.com>
