nipa H/W testing suddenly failing on CX7

[Paolo Abeni]

Hi,

Mat noted that H/W self-tests suddenly started failing on the
mentioned NIC:

https://netdev.bots.linux.dev/flakes.html?min-flip=0&br-cnt=20&br-pfx=net-next-hw&ld-remote=netdev-CX7

Judging from the test output, GRO stopped aggregating and the
driver exposes a single queue?!?

I could not spot anything obviously wrong in the relevant
batch:

https://netdev.bots.linux.dev/branch_deltas/net-next-hw-2026-10-22--00-00.html

Could you please have a look?

Thanks,

Paolo

FWIW I think it's the garbage check added to page pool, which Paolo
already identified. Please ignore.

Side note, I don't think we should be expecting vendors to pay
attention to netdev CI. We can set up a group of community developers
who would be willing / able to jump on such issues if maintainers
are overloaded. Vendor help is obviously welcome if voluntary
but I feel like I implied/promised in the past that the CI will not 
be a burden to vendors, and this email goes against that.
