There don't seem to be many changes going from v2.1.2 to v2.1.3 of lwIP.
Mostly they are:
- IPv6 fixes and improvements
- changes to apps and other code that MicroPython doesn't use
- comments and tests
- minor bug fixes
In particular there doesn't look to be any change to the API of any
function used by MicroPython.
Network multi tests pass on PYBD_SF2 and PYBD_SF6. PYBD_SF2, PYBD_SF6 and
PICO_W have unchanged iperf3 performance. Similar results for networking
on the mimxrt port.
