This is after Fewt submitted a patch that appears to apply for all 0x1660103 devices, Previous PR is no longer required for that SSID.

@CVMagic could you rebase against 6.10/chimeraos for me? They also added the Loki MiniPro there, so I think we need to accomodate there.

'''

This is because BPF trampoline is not implemented on Loongarch yet,
"link" returned by bpf_map__attach_struct_ops() is NULL. test_progs
crashs when this NULL link passes to bpf_link__update_map(). This
patch adds NULL checks for all links in bpf_tcp_ca to fix these errors.
If "link" is NULL, goto the newly added label "out" to destroy the skel.

v2:
 - use "goto out" instead of "return" as Eduard suggested.

Remove the dma_unmap_page_attrs() call in the driver's XDP_REDIRECT
code path.  This should have been removed when we let the page pool
handle the DMA mapping.  This bug causes the warning:

This is the same sort of panic as observed in commit 4224cfd

There are many other callers of __ethtool_get_link_ksettings() which

Move this check into ethtool to protect all callers.
