[Bug 2163419] [NEW] [24.04] Azure MANA NIC fails to probe on linux-6.8: "gdma probe failed: err = -71"

Public bug reported: Description: On Ubuntu 24.04 (linux-6.8) Azure instances, MANA-accelerated NICs fail to initialize during device probing, leaving the network interface unusable. Logs (dmesg): kernel: mana 7870:00:00.0: HWC: Failed hw_channel req: 0xc00000bb kernel: mana 7870:00:00.0: VfVerifyVersionOutput: -71, status=0xc00000bb kernel: mana 7870:00:00.0: gdma probe failed: err = -71 This could be related to missing upstream commit: 7fc45cb68696 ("net: mana: Allow variable size indirection table").
