Elsukov <ae@FreeBSD.org> --- Comment on attachment 148695 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D148695 kernel function for printing mbuf info > printf("mbuf %p: len %u, flags %b\n", m, m->m_len, > m->m_flags, M_FLAG_PRINTF); Nothing specific :( It seems the last what here can be interesting is the following: if (m->m_flags & M_PKTHDR) printf(" hdrlen %u\n", m, m->m_pkthdr.len) > if (m->m_len < sizeof(struct ip)) > return; --=20 You are receiving this mail because: You are the assignee for the bug.=
