RNDIS and DHCPD
First attempt hasn't worked, but not I've investigated or checked my
.config yet; but, before I do, is it reasonable to expect NuttX to
support DHCP server and USB RNDIS such that a connected PC gets an IP
address from the NuttX RNDIS "gadget" allowing connectivity without the
PC user having to change adapter settings (assuming the adapter is set
for DHCP)?
If so, great, I'll persevere. If not, I'll save myself the hassle :)

I think the DHCP server is working, see this tutorial:

I wrote a DHCP server a long time ago. It is at apps/netutils/dhcpd.
Haven't used it in a long time so I would expecit it to have some bit rot.

Good question! Normally the computer/host is supposed to run the DHCP
server, you need to check in the spec if there is some way to change
it.

Will check those configs, thanks Alan. But I want the NuttX device to be
the DHCP server, so the PC gets an IP address in the same subnet as the
NuttX device, assuming the PC is set to get IP addresses via DHCP. I
don't think the PC (Linux or Windows) can give the NuttX device an IP
address without lots of hassle.
My hope is that I can enable my board as a DHCP server and web server:
plug it to a PC (USB/RNDIS), use a browser, and get web pages served
from the device to configure, and get files. This means I don't need USB
MSD and FAT :)

Hi Tim,
Looking my see you can see that I faced some issues with Ubuntu
attributing DHCP address to my board, but I think it works if you use
a better dhcp server on Linux.
I suggest you too look how other boards are configuring it, i.e.:
boards/arm/lc823450/lc823450-xgevk/configs/rndis/defconfig
boards/arm/stm32/stm32f4discovery/configs/rndis/defconfig
BR,
Alan
