I'm not the OP, but I do (sometimes) run head, and have an iwn(4) NIC on
my laptop, so I checked: I was able to reproduce the cited symptoms:


                    /0   /1   /2   /3   /4   /5   /6   /7   /8   /9   /10

As a reality check:

Finally, what you requested:

g1-252(11.0-C)[5] sysctl -a | grep octets
dev.em.0.mac_stats.good_octets_recvd: 0
dev.em.0.mac_stats.good_octets_txd: 0
g1-252(11.0-C)[6] uname -a
FreeBSD g1-252.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #1268  r267149M/267149:1100022: Fri Jun  6 06:00:16 PDT 2014     root at g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY  i386
g1-252(11.0-C)[7] 

(The machine is running head because it's in the middle of a
source-based update to r267211.)

Peace,
david
