DP83TC811S-Q1: multipoint/multidrop/star topology support

We are developing a communication system using DP83TC811S-Q1 ICs. We have recently discovered that the device documentation does not mention multipoint/multidrop/star topology support, which is a feature of the 802.3bw 100BASE-T1 standard. This topology is a requirement in our product design.

We have a couple of questions:

• Can the DP83TC811S be used to send data at half/full duplex from a master to multiple slaves i.e. Star topology?
• In the TI document TIDUET1, Figure 2 shows a daisy chain configuration using two PHYs per node. Our MCU only has one xMII interface. Is there any way to create a daisy chain topology with only one xMII interface? Are there any MII switches/multiplexers ICs that can enable this?
  
  • 
• A presentation on 100BASE-T1/Automotive Ethernet shows a star topology with a switch. Is this star topology with a switch applicable to the DP83TC811 PHY? If so, are there any TI 100BASE-T1 switches available?
  • 
  • The same star topology with a switch is also shown in the TI document TIDUET1, Figure 4
