Help¶

IPv6 fragmentation is disabled by default. This saves memory and should not cause issues normally as we support anyway the minimum length IPv6 packets (1280 bytes). If you enable fragmentation support, please increase amount of RX data buffers so that larger than 1280 byte packets can be received.

Direct dependencies¶

NET_IPV6 && !NET_RAW_MODE && NETWORKING

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
