What size are you seeing that is larger? Even if an mbuf chain comes
down that large, it does NOT form a single packet, it is packetized by

Evidently FreeBSD violates the LSO spec by sending down up to socket
buffer sized TSO segments to the network card. Is there a way to set
this other than reducing net.inet.tcp.sendbuf_max to a compliant value
(64k)? And is there a way to for a device to communicate to the stack
