Hi everyone,
I have noticed my networking statistics appear to be double counting on two
of my FreeBSD 12-CURRENT boxes running r319025. Could someone please help
me to find the problem (I believe it is likely to be a bug in the
networking driver).
I discovered the double counting by comparing the output of "systat
-ifstat" (which reports 988 KB/s) with the output of "iftop -B" (which
reports 491 KB/s). I know that iftop is the correct one, because my
internet speed only gives me around ~500 KB/s unfortunately.
# systat -ifstat -match igb0
...
Interface Traffic Peak Total
igb0 in 988.008 KB/s 988.008 KB/s 36.295 GB
out 16.953 KB/s 16.953 KB/s 295.774 GB
# iftop -i igb0 -B
...
TX: cum: 31.7KB peak:

rates: 9.69KB 7.92KB 7.92KB

The two interfaces in these boxes are:
$ pciconf -lvv | grep igb1 -A4
igb1@pci0:4:0:0: class=0x020000 card=0x00008086 chip=0x15398086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'I211 Gigabit Network Connection'
class = network
subclass = ethernet
$ pciconf -lvv | grep igb0 -A4
igb0@pci0:8:0:0: class=0x020000 card=0x15331849 chip=0x15338086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'I210 Gigabit Network Connection'
class = network
subclass = ethernet
Regards,
Ben
