[lwip-devel] [bug #55078] Add custom data to pbuf struct

[Thomas Kindler]

Follow-up Comment #2, bug #55078 (project lwip):

I use this feature for adding PTP timestamps:

lwipopts.h:

#define LWIP_PBUF_CUSTOM_DATA       \
    u8_t   timestamp_flags;         \
    struct timespec timestamp;

Question:

How do I make sure, that the fields are initialized to zero?

pbuf_init_alloced_pbuf() function only initializes the old members, but leaves
my own field uninitialized.

Perhaps we should add a LWIP_PBUF_CUSTOM_DATA_INIT_HOOK macro or something?
