The patch directory contains patches. However, README.md does not mention them at all.

Also, device netmap is included in GENERIC on 14.x.

There is a race condition on sequencecheck between the main thread and the receiver thread. The main thread calls seqcheck_clear() on RFC2544_RESETTING while the receiver thread calls seqcheck_receive(). seqcheck_receive() tries to update sequence counters and seqcheck_clear() resets its counters. Unfortunately seqcheck_clear() makes a pointer sc_parent NULL transiently in its process, so seqcheck_receive() can touch the NULL pointer and cause a segmentation fault.

We know that a segmentation fault stemming from the race condition occurs on FreeBSD 13.

We probably have to synchronize the threads on RFC2544_RESETTING to avoid the race condition.

The GNUmakefiles should use $DESTDIR with $PREFIX. This can be fixed by #39.

Would you tag version numbers?
