Subject: AW: AW: ixgbe: Regression, unsupported SFP+ modules on 10Gbit/s X520 NIC no longer work with allow_unsupported_sfp=1

Hi,

printk("DEBUG comp_codes_1g: %u\n", comp_codes_1g);

results in:

Feb 18 18:36:09 n128 kernel: [26043.714408] DEBUG comp_codes_1g: 2

Best regards,

Stefan Behte

I've seen some transceivers that have "Code for electronic or
optical compatibility" EEPROM field (see SFF-8472) set to
all-zeroes. Maybe this is your case. Could you please printk
value of comp_codes_1g variable somewhere?
