[illumos-gate] 14959 NVMe namespace management support -- Robert Mustacchi <rm⊙fo>

sommerfeld, danmcd_: The setting advertised speed functions for copper is not a phy thing, but an i40e related bit.

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.

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.

yep, copper SFP for 10G-baseT which works fine with a switch but which results in 85%+ packet loss when connected to the ONT

I'm not sure if the firmware is clever enough to take a speed request and deal with a multi-speed txr.

it shows rw properties for en_5000fdx_cap and en_2500fdx_cap (off) but declines to let me set them on.

other en_*_cap properties are readonly.

10g and 1g are on, others are off.

Yeah, it's because the 2.5/5G stuff was missed from the i40e propinfo.

So it doesn't say read only correctly

Sorry, missed that bit in illumos.org/issues/13334.

Probably some effort could be spent to make those settable and better deal with firmware there.

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.

sort of behaves like a "beat" between two slightly-mistuned frequencies.

looking more closely at system messages I see: " NOTICE: i40e0: The driver for the device detected an older version of the \

NVM image (1.7) than expected (1.9). Please update the NVM image."

oddly, on another -- older -- system, NOTICE: i40e0: The driver for the device detected a newe\

r version of the NVM image (1.15) than expected (1.10).

and it would appear that this is some sort of API version unreleased to the NVM version numbers intel puts in their documentation.

I filed illumos.org/issues/17479

→ BUG 17479: i40e reports en_5000fdx_cap and en_2500fdx_cap as writable when they are not (New)

I can spin a quick change for that if you wouldn't mind testing it sommerfeld.
