To use IPv6 we need proper SLAAC support which is not possible without this option. Compile tested on esp32, esp32s2, esp32s3, esp32c3 Functionality tested in esp32 BasicHttpClient with some minor patches, IPv6 start to work. No significant sketch size increase (probably within rounding bounds): Before: Wrote 875328 bytes (558896 compressed) at 0x00010000 in 9.0 seconds (effective 779.4 kbit/s)... After: Wrote 875328 bytes (558942 compressed) at 0x00010000 in 9.0 seconds (effective 779.8 kbit/s)... This patch part of the efforts mentioned in espressif/arduino-esp32#6242 Proper IPv6 support also was requested in: espressif/arduino-esp32#6626 espressif/arduino-esp32#6590 espressif/arduino-esp32#6283 espressif/arduino-esp32#6703 espressif/arduino-esp32#5624 espressif/arduino-esp32#1261 And many others.
