It works! And provides a full socket implementation. But some performance is lost: with a lot of memory allocated to lwIP it gives Around 750,000 bytes/sec max TCP download, compared with 1M/sec when using the TCP/IP stack on the Wiznet module. TODO: - probably put lwip polling in systick via a pending scheduled event - could update wiznet driver since it fixes the -2 bug and buf size masks that are patched here - update lwip to v2
libaxtls requires the build directory to exist, and lwip's dhcp.c can give warnings on certain gcc versions.
Instead of including sys/types.h which leads to problems with the cc3000 driver.
Dramatically improves TCP sending throughput because without an explicit call to tcp_output() the data is only sent to the lower layers via the lwIP slow timer which (by default) ticks every 500ms.

ethernetif.c --- low level driver mainly derived from STM example code network_ethernet.c --- MicroPython module code Makefile and mpconfigport.mk are modified to build these files modnetwork.c added ethernet
…ip_init becase it would be called from netif_add.

Thanks for submitting this PR. Ethernet support in the stm32 port would be a great addition and I'd be happy to merge this code. Can you please re-open this PR at the main, upstream repository https://github.com/micropython/micropython ? It won't get merged immediately -- there are a few things that need to be fixed/merged first -- but it will go in the queue. |

Thank you for your response. |

asan considers that memcmp(p, q, N) is permitted to access N bytes at each
of p and q, even for values of p and q that have a difference earlier.
Accessing additional values is frequently done in practice, reading 4 or
more bytes from each input at a time for efficiency, so when completing
"non_exist<TAB>" in the repl, this causes a diagnostic:

I normally want to use onboard ethernet with NUCLEO and F7disco.
Is it possible to merge these codes in the micropython/micropyhton master branch?
