Hi,
commit 64f55156f7adedb1ac5bb9cdbcbc9ac05ff5a724 upstream
The requested patch allows the iwlwifi driver to work with newer AX200
wifi cards when MSI-X interrupts are not available. Without it,
bringing an interface "up" fails with a Microcode SW error. Xen PCI
passthrough with a linux stubdom doesn't enable MSI-X which triggers
this condition.
I think it's only applicable to 5.4 because it's in 5.10 and earlier
kernels don't have AX200 support.
I'm making this request to stable and CC-ing netdev since I saw a
message [1] on netdev saying:
"""
We're actually experimenting with letting Greg take networking patches
into stable like he does for every other tree. If the patch doesn't
appear in the next stable release please poke stable@ directly.
"""
Thanks,
Jason
