Mellanox ConnectX-5 Firmware RequirementsΒΆ
Mellanox ConnectX-5 network interface cards (mlx5) in the MT27800 family are
currently shipping with firmware revision 16.26.1040 which is not compatible
with TNSR.
The incompatible firmware can be identified by errors in the log (e.g. sudo
vppctl show errors), such as:
net_mlx5: probe of PCI device [PCI ID] aborted after encountering an error: Operation not supported
Or:
Interface WAN error -12: Unknown error -12
net_mlx5: Failed to query QP using DevX
net_mlx5: Fail to query port 0 Tx queue 0 QP TIS transport domain
net_mlx5: port 0 Tx queue allocation failed: Cannot allocate memory
Device with port_id=0 already stopped
Firmware version 16.24.1000 is compatible with TNSR, and can be manually
downgraded using the following procedure.
First, identify the first PCI ID of the card in question. This can be found by
looking in the boot logs, the output of a utility such as lspci, or similar
methods. The ID will take the form of xx:yy.z, for example 65:00.0. The
ID will be used in the following set of commands.
Next, download and decompress the appropriate firmware:
$ curl -LO http://www.mellanox.com/downloads/firmware/fw-ConnectX5-rel-16_24_1000-MCX516A-CCA_Ax-UEFI-14.17.11-FlexBoot-3.5.603.bin.zip
$ unzip fw-ConnectX5-rel-16_24_1000-MCX516A-CCA_Ax-UEFI-14.17.11-FlexBoot-3.5.603.bin.zip
Now install the Mellanox firmware tool and perform the firmware downgrade:
$ sudo yum install mstflint
$ sudo mstconfig q > mst.log
$ sudo mstfwmanager -d <PCI ID> -u -f -i fw-ConnectX5-rel-16_24_1000-MCX516A-CCA_Ax-UEFI-14.17.11-FlexBoot-3.5.603.bin
Replace <PCI ID> in the last command with the first PCI ID of the card.
With the appropriate firmware loaded on the card, it will no longer produce errors and it will be usable by TNSR.
Warning
Reboot after performing the firmware downgrade to ensure the card is fully reinitialized with the appropriate firmware.
