I installed the mlnx-en-23.10-0.5.5.0-rhel9.2-x86_64.tgz driver for the Mellanox ConnectX-5 card on the Rocky OS and completed the installation using the install script (./install --add-kernel-support --dpdk). The QSFP28 port of this card is connected to four 10G switch ports via a breakout cable. The installation was successful, but the card is seen as InfiniBand in ifconfig, not as a normal Ethernet port. Is this normal, and how can I change it to Ethernet? Also, can I run a DPDK forwarding application with a 4x10G breakout cable?
If there are 4 different 10G connections on a single port, shouldn’t I see 4 different interfaces for each port? If, when using the ‘ifconfig’ command, I only see an interface recognized as InfiniBand, there might be driver or configuration issues.
