This series adds CDX bus support to the MANA driver. The shared GDMA and Ethernet code currently builds together with the PCI transport. To add another bus without duplicating the driver or adding configuration checks throughout the shared code, this series separates the bus-specific operations and builds each transport independently.
Patch 1 introduces gdma_bus_ops and routes bus-specific interrupt, reset, service, and setup operations through it. Patch 2 moves the PCI-specific code from gdma_main.c into gdma_pci.c without changing PCI behavior. Patch 3 builds the shared code as gdma_core.ko and the PCI transport as mana.ko. The PCI module keeps its existing name, device table, and mana.eth/mana.rdma auxiliary-device identities. Patch 4 adds the CDX transport as mana_cdx.ko for device ID 0x00C2.
