Wake on lan via phy activity

I am trying to enable wake on lan via phy activity which I would assume any network access to this network card should wake it.

I can wake on lan via magic packet and that works

sudo ethtool enp4s0

Settings for enp4s0:

        Supported ports: [  ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
                                2500baseT/Full
        Supported pause frame use: Symmetric
        Supports auto-negotiation: Yes
        Supported FEC modes: Not reported
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
                                2500baseT/Full
        Advertised pause frame use: Symmetric
        Advertised auto-negotiation: Yes
        Advertised FEC modes: Not reported
        Speed: 2500Mb/s
        Duplex: Full
        Auto-negotiation: on
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: internal
        MDI-X: off (auto)
        Supports Wake-on: pumbg
        Wake-on: p
        Current message level: 0x00000007 (7)
                               drv probe link
        Link detected: yes

I have modified /etc/network/interfaces to add the "p" option so it should wake on phy activity instead of magic packet

auto lo
iface lo inet loopback

iface enp4s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.12/24
        gateway 192.168.1.1
        bridge-ports enp4s0
        bridge-stp off
        bridge-fd 0
        up ethtool -s enp4s0 wol p

I can try to ping 192.168.1.12 from a windows machine and this machine does not wake. If I switch it back to wake on magic packet it boots every time

Wake on magic is how it is supposed to work. https://www.energystar.gov/products/low_carbon_it_campaign/implementation_resources_enterprises/wake_on_lan#:~:text=Wake%2Don%2DLAN%20(WOL,reserved%20for%20the%20network%20card.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
