Subject: [PATCH V4 13/26] bnx2x: deprecate pci_get_bus_and_slot()
Date: Tue, 19 Dec 2017 00:37:49 -0500 [thread overview]
Message-ID: <1513661883-28662-14-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1513661883-28662-1-git-send-email-okaya@codeaurora.org>
pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.
Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().
Introduce bnx2x_vf_domain() function to extract the domain information
and save it to VF specific data structure.
Use the saved domain value while calling pci_get_domain_bus_and_slot().
