Hello!


The function always returns an error and remove the chain MBUF for two or
more generated on the same host.
If the pre-call m_defrag no error occurs.
This is normal behavior?
How to know in advance the maximum size for MBUF that does not cause a
failure in m_pullup?


mbuf: 0xfffffe0074fc0600 len: 42, next: 0xfffffe0073a45800, 2<pkthdr>
mbuf: 0xfffffe0073a45800 len: 210, next: 0, 1<ext>
FAIL: m_pullup: m_pkthdr.len = 252, m_len = 42, pullup_len = 252
