I used USB 3 Gen X CV (downloaded from usb.org 1-2 week ago). Tests are:
1. "Device Summary" - after 1st pass, disconnect then connect again test
failed. Actually it show as "test passed" but not able to enumerate
device again.
2. MSC "USB Mass Storage Power Up Test". After disconnect, by suite
request, and then connect test failed (pass, if reloading driver).

dwc2 driver resetting DEVADDR in DCFG register only in function
dwc2_hsotg_core_init_disconnected() by soft reset. This function not
called on disconnect/connect with CV SW stack (function call not seen in
dmesg).
This issue not seen with any other EHCI/XHCI hosts either on
Linux/Windows because these hosts issuing USB RESET, as result called
dwc2_hsotg_core_init_disconnected().

In dwc3 per my understanding same stuff done in function
dwc3_gadget_reset_interrupt(), am I right?

Yes, this issue not seen with dwc3.
