    Intel XL710-QDA2 can no longer be changed to 2x40 or 1x40 mode with latest firmware 5.02

    Joeri

      The 40Gb modes can no longer be selected using the qcu64e utility since the firmware upgrade from 4.42 to 5.02. Only 4x10 and 2x2x10 options are offered but the XL710-QDA2 card is QSFP+ capable.

       

      # qcu64e /NIC=1 /INFO

      Intel(R) QSFP+ Configuration Utility

       

      QCU version: v2.26.17.06

      Adapter supports QSFP+ Configuration modification.

      Current Configuration: 4x10

       

      Supported Configurations:

      4x10

      2x2x10A (Top 2 lanes on Module0; Bottom 2 lanes on Module 1)

      2x2x10B

       

      Cards that already are in 40Gb mode continue to function in 40Gb mode, but they report invalid configuration with qcu64e:

      # qcu64e -nic=1 -info

      Current Configuration: Invalid

       

      Supported Configurations:

      4x10

      2x2x10A (Top 2 lanes on Module0; Bottom 2 lanes on Module 1)

      2x2x10B

       

      We are using the i40e driver 1.4.25 on Redhat 6: 2.6.32-573.18.1.el6.x86_64 kernel

      # ethtool -i eth4

      driver: i40e

      version: 1.4.25

      firmware-version: 5.02 0x80002285 0.0.0

      bus-info: 0000:06:00.0

      supports-statistics: yes

      supports-test: yes

      supports-eeprom-access: yes

      supports-register-dump: yes

      supports-priv-flags: yes

       

      It looks like there is currently no way to downgrade the firmware, which make the cards that are now stuck in 4x10 unusable for us.
