LTC4269-1 for LLDP protocol

Hi,

According to LTC4269-1 datasheet,

a Type 2 PD must be able to recognize both layers of communications and identify a Type 2 PSE.

According to IEEE802.3at-2009,

Type 2 PDs implement both 2-Event Physical Layer classification (see 33.3.5.2) and Data Link Layer
classification (see 33.6) and advertise a 2-Event class signature of 4.

Will LTC4269-1 recognize PSE through data layer negotiations ?

Or need change PSE register bit through Physical Layer ?

Thanks a lot !
