Raspberry Pi 4 Model B Rev 1.1 - DHCP issue on boot.

After recent upgrade the DHCP option in Netconf no longer gets an IP address / nor does it enable eth0.
- I think this started after around mid October... updates I'm no longer getting address on reboot.

Pi4 - plugged in to switch on eth0 had previously worked well ...

PI4 - just reloaded to today's current 11-12-2023 followed the directions and performed a clean install.
same results

I checked /etc/rc.d/rc.inet1.conf
and pretty much only ( USE_DHCP[0]="yes" ) is set.

Here is the dmesg from boot.

I can resolve the issue by adding this to rc.local
but wanted to let you know of this new behavior.

Code:# check eth0 if down bring up
if [[ $(cat /sys/class/net/eth0/operstate) == "down" ]] ;then
/sbin/ifconfig eth0 up
/sbin/dhcpcd eth0
fi
If you can think of anything to try let me know.
