Hi All, Is it safe to assume that when a driver receives an Ethernet frame to transmit with CSUM_TSO bit set in m_head->m_pkthdr.csum_flags ; where m_head is the first (struct mbuf) in the mbuf chain that the [Ethernet Header] + [VLAN Tag if present] + [IP Header] + [TCP Header] are all present in one physically contiguous segment ? In other words is Size of ([Ethernet Header] + [VLAN Tag if present] + [IP Header] + [TCP Header]) <= m_head->m_len When ((m_head->m_pkthdr.csum_flags & CSUM_TSO) != 0) Thanks David S.
