Content of the Type of Service octet

Although obsoleted by [RFC2474], traditional use of the Type of Service octet as described in [RFC791] is still common.

idiomatic.tc defines the following fields:

ip_tos_prec are the upper three bits of ip_tos.

ip_tos_delay is the bit that, if set, indicates the desire for short delay.

ip_tos_throughput is the bit that, if set, indicates the desire for high throughput.

ip_tos_reliability is the bit that, if set, indicates the desire for high reliability.
