if you get this errors when you try to install the drivers with the kernel 6.5 on ubuntu 23.10 :

 

Check old driver and unload it.

you have to edit some sources files :

1) error : pci_set_dma_mask, pci_set_consistent_dma_mask & netif_set_gso_max_size:

edit file r8125_n.c

 

replace pci_set_dma_mask(pdev, DMA_BIT_MASK(64))

by dma_set_mask(&pdev->dev, DMA_BIT_MASK(64))

 

replace pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(64))

by dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))

 

replace netif_set_gso_max_size(dev, LSO_64K)

by netif_set_tso_max_size(dev, LSO_64K)
