15:19:08 <rmustacc> sommerfeld, danmcd_: The setting advertised speed functions for copper is not a phy thing, but an i40e related bit.
15:19:33 <rmustacc> But if it's actually an SFP plugging into it that goes out to the device, then I think that's going to be more about i40e firmware off hand.
15:20:02 <rmustacc> If we think we're running at 10G hard to say exactly what's going on, but i40e just gets a blob of speed info back from the device firmware.
15:40:24 <sommerfeld> yep, copper SFP for 10G-baseT which works fine with a switch but which results in 85%+ packet loss when connected to the ONT  
15:41:50 <rmustacc> I'm not sure if the firmware is clever enough to take a speed request and deal with a multi-speed txr.
15:42:07 <sommerfeld> it shows rw properties for  en_5000fdx_cap and  en_2500fdx_cap (off) but declines to let me set them on.
15:42:23 <sommerfeld> other en_*_cap properties are readonly.
15:42:53 <sommerfeld> 10g and 1g are on, others are off.
15:43:23 <rmustacc> Yeah, it's because the 2.5/5G stuff was missed from the i40e propinfo.
15:43:28 <rmustacc> So it doesn't say read only correctly
15:44:24 <rmustacc> Sorry, missed that bit in https://www.illumos.org/issues/13334.

15:45:33 <rmustacc> Probably some effort could be spent to make those settable and better deal with firmware there.
15:53:06 <sommerfeld> more interesting question for me is what's causing the packet loss at 10G.  when running a ping, the loss (or, well, the non-loss) comes in waves - long stretches of nothing getting through alternating with shorter periods where it works for a handful of seconds.
15:55:42 <sommerfeld> sort of behaves like a "beat" between two slightly-mistuned frequencies.
16:08:33 <sommerfeld> looking more closely at system messages I see:  " NOTICE: i40e0: The driver for the device detected an older version of the \
16:08:33 <sommerfeld> NVM image (1.7) than expected (1.9). Please update the NVM image."
16:46:11 <sommerfeld> oddly, on another -- older -- system, NOTICE: i40e0: The driver for the device detected a newe\
16:46:12 <sommerfeld> r version of the NVM image (1.15) than expected (1.10).
16:46:38 <sommerfeld> and it would appear that this is some sort of API version unreleased to the NVM version numbers intel puts in their documentation.
19:56:42 <sommerfeld> I filed https://www.illumos.org/issues/17479
19:56:43 <fenix> → BUG 17479: i40e reports en_5000fdx_cap and  en_2500fdx_cap as writable when they are not (New)
20:19:50 <rmustacc> I can spin a quick change for that if you wouldn't mind testing it sommerfeld.
