xn(4) seems to be working for me on a RootBSD vm.  ixlv(4) seems to be working
for others and this should not longer be a problem in 12-CURRENT and the
11.2-RELEASE images.  Please retest if you wish at your earliest convenience.

(In reply to pete from comment #15)

I've just encountered this missing TX issue on AWS with the xn0 driver:

$ uname -v

I'm glad to see that other people have reproduced this issue and that it's not
only something that I have experienced.

Change title back. xn(4) was an unrelated issue that only looked similar.

Re-assign to more appropriate ML (freebsd-net), cc'ing original ML
(virtualization).

(In reply to a.andersson.thn from comment #9)
I have not made much progress on my end unfortunately, like you though I'm keen
to test out patches as this is effecting my production systems in AWS.  For now
I'm using cloudwatch metrics for network utilization metrics as a workaround
but would prefer to have the OS report this data correctly.

--- Comment #8 from p...@nomadlogic.org ---
a couple of observations as i've had a few cycles to take a look at
ixgbe/if_ix.c and ixgbe/if_ixv.c source.

1) It looks like both drivers are only populating rx_bytes SYSCTL statistic,
but rx and tx packets counters are defined (and are updating as per testing on
my dev machines).

- I've found that other drivers such as ixl do populate rx and tx byte
counters.

2) the if_ixv code does *not* have any code to populate the OS statistics
structure as per previous comment.  There *is* code in the if_ix.c though, so
perhaps it is easy to port that to the if_ixv device?  My suspicion is that
adding this functionality will fix userland tools.

Since I'm pretty green when it comes to hacking device drivers I'm going to
play with adding tx_bytes to SYSCTl and seeing how that goes.  If anyone with
more experience hacking on drivers wants to take a stab at getting stats in
there I'd be more than happy to test :)

There is lack of statistic counters update in the ixv driver.
I'm not sure and unable to test, but probably you can add several
IXGBE_SET_XXX() macro in the ixv_update_stats() like in the
ixgbe_update_stats_counters().
Also, probably if_setgetcounterfn() should be used to set custom
if_get_counter() handler and IFCAP_HWSTATS caps added to if_capabilities.
