Hello!
During summer I've been working on the driver for "OPEN Alliance 10BASE-T1x
MAC-PHY Serial Interface" compatible SPI MAC-PHYs. These are devices that
communicate Ethernet over one unshielded
twisted pair and that use SPI to interface with the host MCU.
I am not entirely finished with the matter as there is a tool for PLCA
configuration to be implemented into nuttx apps
and of course a great deal of documentation to be written. But at this stage I
would like to try and integrate the parts
I consider finished for now. These are the base driver (implementation of
shared protocol logic), support for the Onsemi
NCV7410 (NCN26010) and the Microchip LAN865x MAC-PHYs (chip-specific features),
and support for the driver on ESP32-C6
boards and the SAMV7 Xplained ultra board.
There is currently support for the NCV7410 MAC-PHY in NuttX mainline that is a
product of my prior effort. Although I
used this old driver as a starting point, the new driver has developed into
something a bit different and there is a
naming clash between the new and the old, therefore the old has to be removed
first.
I propose the following pull request strategy:
1. PR:
1. commit: boards/risc-v/esp32c6: Remove board support for the NCV7410
2. commit: drivers/net: Remove the NCV7410 10BASE-T1S MAC-PHY driver
2. PR:
1. commit: net/netdev/netdev_ioctl.c: Add new ioctls for MMD register access
3. PR:
1. commit: drivers/net: Add base driver for the OA-T6 protocol MAC-PHYsS
2. commit: drivers/net/oa_tc6: Add
driver for the Onsemi NCV7410 (NCN26010)
3. commit: drivers/net/oa_tc6: Add driver for the Microchip LAN865x
4. PR:
1. commit: boards/risc-v/esp32c6: Add support for the OA-TC6 10BASE-T1x
MAC-PHYs
2. commit: boards/arm/samv7/samv71-xult: Add support for the OA-TC6
10BASE-T1x MAC-PHYs
All 8 commits are temporarily held at my github here:

The first PR is on the way.
Have a pleasant start of the week
