35/*
36 * Bitmap of input ports
37 *
38 * The representation is not straightforward, but it works with existing OXM
39 * semantics.
40 *
41 * The value should always be zero. The mask should be unset in every bit position
42 * where the corresponding input port is allowed, and set in all other bits.
43 * As a special case, the highest bit in the mask is reserved for higher port
44 * numbers than can be represented in the bitmap.
45 *
46 * The value1 and value_mask1 fields contain the most significant bits. value2
47 * and value_mask2 contain the least significant bits.
48 *
49 * Pseudocode for populating value or mask:
50 * bitmap |= in_port < 128 ? (1 << in_port) : (1 << 127)
