Hi Alex,
I was looking for the SIOCGI2C socket ioctl API, and did not find it in the
intel driver. Which led me to believe this was the reason for me not seeing the
SFP data.
But after correctly looking up the SFP info (the port was in a different jail,
which confused me), it turns out that it's not Intel NIC, but Qlogic CNA who
are not providing this info when in IP mode.
slot 0: 1G/10G Ethernet Controller CNA EP 8324
(Dual-port, QLogic CNA 8324(8362) rev. 2)
e0f MAC Address: 00:a0:98:ef:a9:4c (auto-10g_twinax-fd-up)
e0e MAC Address: 00:a0:98:ef:a9:4b (auto-10g_twinax-fd-up)
Device Type: EP8324N
Firmware Version: 5.4.66.0
ql0@pci0:14:0:0: class=0x020000 card=0xfb051275 chip=0x88301077 rev=0x02
hdr=0x00
vendor = 'QLogic Corp.'
class = network
subclass = ethernet
Which is the driver qlxgbe...

Hi Richard,
which Intel nics you're referring to? IIRC ixgbe/ixl SIOCGI2C support was added
5? years ago.
