###### EXPLANATION
# See 'INGRESS' below for information about incoming packets. All of this
# except for that refers to queueing outgoing packets.
#
# Most of what is sent goes out on a randomly selected high SOURCE port
# ('sport') to a specific DESTINATION port ('dport'). For example, an http
# request is sent with 'dport' = 80 and 'sport' = random. Therefore, 'sport'
# specifications are rarely applicable. The port number is located in the
# packet header and is specified thus:
# "u32 match ip dport PORT# 0xffff" or "u32 match ip sport PORT# 0xffff"
#
# Since shaping means quequeing OUTGOING packets, your IP Address(es) are
# SOURCEs ('src') and the remote machine's IP Address(es) are DESTINATIONs
# ('dst') - so, as with 'sport', 'src' specifications are rarely applicable.
# The IP Address is located in the packet header and is specified thus:
# "u32 match ip src IP-ADDRESS" or "u32 match ip dst IP-ADDRESS"
#
# Read the HOWTO "All the filtering commands you will normally need" for
# protocol information (TCP, UDP, ICMP, GRE, IPSEC). Also see the TOS and
# ICMP sections below.
