--- Patch [1]: [PATCH v6 1/1] rust: pci: add extended capability and SR-IOV support ---
commit 69f27ed67b8e8dbe83e8e431269f12c739076818
Author: Zhi Wang <zhiw@nvidia.com>
Subject: rust: pci: add extended capability and SR-IOV support

This commit adds support for locating and projecting PCIe extended capabilities
in the Rust PCI abstraction. It defines a typed layout for the SR-IOV extended
capability and adds helpers to decode VF BARs.

[Severity: Low]
This isn't a bug, but should this function be annotated with #[inline]?

The Rust subsystem guidelines specify that small functions or functions
forwarding to a binding call within abstractions should be annotated with
#[inline].
