Hi, A change in mb_free_ext() introduced in FreeBSD 11 versions broke the transmission support for netmap in emulated mode. This means immediate kernel crashes for netmap users in non-native (emulated) mode. This problem has been fixed in FreeBSD-12-CURRENT, which contains a recent version of Netmap. However, FreeBSD 11 versions (release, stable) are still affected, as they contain old Netmap versions. Is it possible to push the fix (provided by me) to the relevant release/stable branches? What is the procedure (I'm not familiar with the FreeBSD release engineering process)? Thanks, Vincenzo
