CONFIG_NET_HEADERS_ALWAYS_CONTIGUOUS
¶
(No prompt – not directly user assignable.)
Type: bool
Help¶
This a hidden option, which one should use with a lot of care. NO bug reports will be accepted if that option is enabled! You are warned. If you are 100% sure the headers memory space is always in a contiguous space, this will save stack usage and ROM in net core. This is a possible case when using IPv4 only, with NET_BUF_FIXED_DATA_SIZE enabled and NET_BUF_DATA_SIZE of 128 for instance.
Defaults¶
No defaults. Implicitly defaults to n
.
