dpdk-kmods-dkms fails to build on kinetic with latest 5.19 kernel

[Impact]

dpdk-kmods-dkms fails to build on kinetic kernel 5.18+ with the following error:

/var/lib/dkms/dpdk-kmods/0~20220111+git/build/igb_uio.c:515:15: error: implicit declaration of function ‘pci_set_dma_mask’; did you mean ‘ipi_send_mask’? [-Werror=implicit-function-declaration]
  515 | err = pci_set_dma_mask(dev, DMA_BIT_MASK(64));
      | ^~~~~~~~~~~~~~~~
      | ipi_send_mask
/var/lib/dkms/dpdk-kmods/0~20220111+git/build/igb_uio.c:521:15: error: implicit declaration of function ‘pci_set_consistent_dma_mask’ [-Werror=implicit-function-declaration]
  521 | err = pci_set_consistent_dma_mask(dev, DMA_BIT_MASK(64));
      | ^~~~~~~~~~~~~~~~~~~~~~~~~~~

[Test case]

$ sudo apt install dpdk-kmods-dkms

[Fix]

Provide pci_set_dma_mask / pci_set_consistent_dma_mask ABI also in kernels >= 5.18.

[Regression potential]

We may see regressions of this driver (dkdp-kmods-dkms) in kernels >= 5.18.

[Andrea Righi (arighi)]

Fix (debdiff) in attach provides the right interfaces to build this module in kernels >= 5.18.

[Dimitri John Ledkov (xnox)]

Very confused why this module is not upstreamed, or maintained.

Have you forwarded this patch to dpdk at http://git.dpdk.org/dpdk-kmods ?
