Detailed Description

Macro Definition Documentation

◆ LWIP_PBUF_CUSTOM_DATA

#define LWIP_PBUF_CUSTOM_DATA

LWIP_PBUF_CUSTOM_DATA: Store private data on pbufs (e.g. timestamps) This extends struct pbuf so user can store custom data on every pbuf.

Definition at line 1615 of file opt.h.

◆ LWIP_PBUF_REF_T

#define LWIP_PBUF_REF_T   u8_t

LWIP_PBUF_REF_T: Refcount type in pbuf. Default width of u8_t can be increased if 255 refs are not enough for you.

Definition at line 1607 of file opt.h.

◆ PBUF_LINK_ENCAPSULATION_HLEN

#define PBUF_LINK_ENCAPSULATION_HLEN   0

PBUF_LINK_ENCAPSULATION_HLEN: the number of bytes that should be allocated for an additional encapsulation header before ethernet headers (e.g. 802.11)

Definition at line 1590 of file opt.h.

◆ PBUF_LINK_HLEN

#define PBUF_LINK_HLEN   (14 + ETH_PAD_SIZE)

PBUF_LINK_HLEN: the number of bytes that should be allocated for a link level header. The default is 14, the standard value for Ethernet.

Definition at line 1581 of file opt.h.

◆ PBUF_POOL_BUFSIZE

PBUF_POOL_BUFSIZE: the size of each pbuf in the pbuf pool. The default is designed to accommodate single full size TCP frame in one pbuf, including TCP_MSS, IP header, and link header.
