flow
++++

Flow filter supports two types of modes::
    - map
    - hash

# Prepare a Qdisc with fq-codel
    ip.tc("add", "fq_codel", ifb0,
          parent=0x10001, handle=0x10010)

# Create flow filter with hash mode
    # Single:
    keys = "src"
    # Multi (comma separated list of keys):
    keys = "src,nfct-src"
    ip.tc("add-filter", "flow", ifb0,
          mode="hash", keys=keys,
          divisor=1024, perturb=60,
          handle=0x10, baseclass=0x10010,
          parent=0x10001)

# Create flow filter with map mode
    # Simple map dst with no OP:
    ip.tc("add-filter", "flow", ifb0,
    mode="map", key="dst",
    divisor=1024, handle=10
    baseclass=0x10010)

# Same filter with xor OP:
    ops = [{"op": "xor", "num": 0xFF}]
    ip.tc("add-filter", "flow", ifb0,
    mode="map", key="dst",
    divisor=1024, handle=10
    baseclass=0x10010, ops=ops)

# Complex one with addend OP (incl. minus support):
    ops = [{"op": "addend", "num": '-192.168.0.0'}]
    ip.tc("add-filter", "flow", ifb0,
    mode="map", key="dst",
    divisor=1024, handle=10
    baseclass=0x10010, ops=ops)

# Example with multiple OPS:
    ops = [{"op": "and", "num": 0xFF},
           {"op": "rshift", "num": 4}]
    ip.tc("add-filter", "flow", ifb0,
    mode="map", key="dst",
    divisor=1024, handle=10
    baseclass=0x10010, ops=ops)

NOTES:
    When using `map` mode, use the keyword `key` to pass a key.
    When using `hash` mode, use the keyword `keys` to pass a key
    even if there is only one key.
    In `map` mode, the `num` parameter in `OPS` is always an
    integer unless if you use the OP `addend`, which can be
    a string IPv4 address. You can also add a minus sign at
    the beginning of the `num` value even if it is an IPv4
    address.
