Hi!

I'm using Dirk Ziegelmeier's commit 92a18b (Bug #55078) for adding PTP
timestamps:

lwipopts.h:

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

Unfortunately, there's no official way to initialize the new fields.
pbuf_init_alloced_pbuf() function only initializes the old members, but leaves
my own fields uninitialized.
