[PATCH 2/9] e1000e: Remove redundant pci_enable_pcie_error_reporting()

[PATCH 2/9] e1000e: Remove redundant pci_enable_pcie_error_reporting()

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@google.com>

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this doesn't control interrupt generation by the Root Port; that
is controlled by the AER Root Error Command register, which is managed by
the AER service driver.

Thanks a million for taking a look at these, Tony!

These driver patches are all independent and have no dependency on the
1/9 PCI/AER patch.  What's your opinion on merging these?  Should they
go via netdev?  Should they be squashed into a single patch that does
all the Intel drivers at once?

I'm happy to squash them and/or merge them via the PCI tree, whatever
is easiest.

Since there's no dependency, IMO, it'd make sense to go through 
Intel-wired-lan/netdev. Keeping them per driver is fine.

Ah, damn, I spammed Bjorn with the same question because email was
pooped most of the day :/ Reportedly not vger, email in general but 
fool me once...

Tony, if you could take these via your tree that'd be best.

How would you like to route these? Looks like there's no dependency 
so we can pick them up?

Right, no dependencies, so you can pick them up.  Sounds like you and
Tony have it worked out.  Thanks!

[PATCH 9/9] ixgbe: Remove redundant pci_enable_pcie_error_reporting()

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@google.com>

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this doesn't control interrupt generation by the Root Port; that
is controlled by the AER Root Error Command register, which is managed by
the AER service driver.

[+cc all the folks I forgot to cc when sending the original cover

the driver patches]

Thank you very much for reviewing and testing these.  I applied the
first (PCI/AER) patch to the PCI tree.

I think Jakub is planning to merge the rest via the netdev tree.
There are no dependencies, so they can be squashed if desired.  Let me
know if you'd prefer me to merge them or squash them.
