From: Mark Rustad <[email protected]> This patch skips the PCI transactions pending check in ixgbe_disable_pcie_master. This is done to addresses a known HW issue where the PCI transactions pending bit sticks high when there are pending transactions. HW engineering instructed to workaround this issue by wait and then continue with our reset flow.
