The object provides a way to prevent HOL (Head Of Line) blocking
between ports. HOL protection may prevent forwarding a packet to a
blocking port. The idea relies on the assumption that it is better
to discard packets destined to blocking ports, then to let them
consume more and more buffers in the input-port's Rx-counters
because eventually these input ports may become totally blocked.
The meanings of the values are:
other(1) - this entry is currently in use but the conditions under
which it will remain so are different from each of the
following values.
disabled(2) - HOL function disable.
enabled(3) - HOL function enable.
