mlxsw: spectrum_trap: Register 802.1X packet traps with devlink
Register the previously added packet traps with devlink. This allows
user space to tune their policers and in the case of the locked port
trap, user space can set its action to "trap" in order to gain
visibility into packets that were discarded by the device due to the
locked port check failure.
