200k is a lot.
Interestingly I started with the ethernet setup and my intention was ethernet
only, but in the meantime I do need wifi as well.
Anyways, ethernet is started and wifi compiled in as well.
There was a problem (in my old nuttx codebase at least) that the ESP32_emac
code didn't like to be compiled with CONFIG_ARCH_PHY_INTERRUPT, which the
wifi enable enforced.
I dissabled that in the esp32_emac code.
However, I have ethernet started and wifi compiled in, but not started and
that's my meminfo:
total used freelargest nused nfree
Umem: 230384 19120 211264 12995
So some RAM must have been added somewhere else.
