Liang reported an issue where setting a slave’s actor_port_prio to
predefined values such as 0, 255, or 65535 would cause a system crash.
The problem occurs because in bond_opt_parse(), when the provided value
matches a predefined table entry, the function returns that table entry,
which does not contain slave information. Later, in
bond_option_actor_port_prio_set(), calling bond_slave_get_rtnl() leads
to a NULL pointer dereference.
Since actor_port_prio is defined as a u16 and initialized to the default
value of 255 in ad_initialize_port(), there is no need for the
bond_actor_port_prio_tbl. Using the BOND_OPTFLAG_RAWVAL flag is sufficient.
