Move bnx2 driver to linux-modules package or add module-extra dependency for ibm-gt-opt

[Po-Hsu Lin]

Issue found on node rizzo with 6.5.0-1003-ibm-gt-opt

This bare-metal node is using an Ethernet controller from Broadcom, which will need "bnx2" module to work

02:00.0 Ethernet controller [0200]: Broadcom Inc. and subsidiaries NetXtreme II BCM5716 Gigabit Ethernet [14e4:163b] (rev 20)
 DeviceName: Embedded NIC 1
 Subsystem: Dell NetXtreme II BCM5716 Gigabit Ethernet [1028:02a3]
 Flags: bus master, fast devsel, latency 0, IRQ 16
 Memory at da000000 (64-bit, non-prefetchable) [size=32M]
 Capabilities: <access denied>
 Kernel driver in use: bnx2
 Kernel modules: bnx2

However this module is available in the linux-module-extras package. When installing the kernel-testing--linux-ibm-gt-opt--full--ibm-gt-opt virtual package for SRU, this package is not bundled with dependency setting. Therefore the system will be booted without network.

I think this is affecting node onibi as well.

Note that for Jammy 5.15, this module is in modules-extra package as well:
$ dpkg -S bnx2.ko
