CONFIG_NET_IPV6_FRAGMENT

Support IPv6 fragmentation

Type: bool

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.
