--dscp=DSCP Set DSCP value in outgoing IP packets of
BitTorrent traffic for QoS. This parameter sets
only DSCP bits in TOS field of IP packets,
not the whole field. If you take values
from /usr/include/netinet/ip.h divide them by 4
(otherwise values would be incorrect, e.g. your
CS1 class would turn into CS4). If you take
commonly used values from RFC, network vendors'
documentation, Wikipedia or any other source,
use them as they are.
