Subject: [PATCH V1 0/2] Enable TPH support in BNXT driver

Hi All,

TPH (TLP Processing Hints) is a PCIe feature that allows endpoint devices
to provide optimization hints for memory-targeted requests. TPH support
is now available in pci.git/next and ready for v6.13.

This patchset enables TPH in the Broadcom bnxt driver. Through the IRQ
affinity notifier, steering tags (ST) are updated when the driver's IRQ
affinity changes. On Broadcom NICs with compatible firmware, this
implementation improves memory bandwidth efficiency and network
performance in real-world benchmarks.

Note: These patches are follow-ups from the earlier TPH enablement
series. Patch #4 (IRQ affinity) has been updated based on feedback from
Jakub Kicinski. Since net-next currently lacks TPH support, we propose
these patches be merged via pci.git/next after review by Jakub and
others.

Thanks,
-Wei
