Hmm, okay. So what is the output of dladm show-linkprop on that device?
Also, can you grab the prtconf -d /dev/ixgbe<num> output for it?
ixgbe0 adv_10gfdx_cap r- 1 1 1,0
ixgbe0 en_10gfdx_cap rw 1 1 1,0
Okay, so importantly we think we're advertising 10g. I have a feeling
that this part may have a similar bug as the X550 did in the driver.
Here's a way to test this. Run these two commands, waiting a second or
two inbetween and then check the new advertised speed:
dladm set-linkprop -p en_10gfdx_cap=0 ixgbe0
dladm set-linkprop -p en_10gfdx_cap=1 ixgbe0
I don't quite have a system in front of me, so not entirely sure that's
the right command. I'd expect each of those to cause the link to
reconfigure and hopefully we'll see a 10g speed after the second one.
Indeed it does - I could see the indicators on the switch go green.
# dladm show-linkprop -p speed ixgbe0
LINK PROPERTY PERM VALUE DEFAULT POSSIBLE
ixgbe0 speed r- 10000 10000 --
Okay, can I get the prtconf -d /dev/ixgbe0 output from that system?

For reference, the PCIe card:
pci8086,1 (pciex8086,1528) [Intel Corporation Ethernet Controller
