lwIP version: 1.4.1 => git head

Follow-up Comment #4:
I failed to reproduce this because the lwipopts.h of example_app redefined
PBUF_LINK_HLEN to 16.
But still now I can only reproduce this when setting PBUF_POOL_BUFSIZE to
1500, not 1514. While this is still a problem on our side, it seems like your
driver might be using PBUF_LINK to allocate rx pbufs, not PBUF_RAW?
Anyway, this bug still exists when setting PBUF_POOL_BUFSIZE to 1500 (and not
messing with PBUF_LINK_HLEN).
