[dpdk-dev] [PATCH 32/37] ixgbe/base: specific process for X550 and X550em when disabling PCIe master

[Wenzhuo Lu]

This patch skips the PCI transactions pending check in
ixgbe_disable_pcie_master. The PCI transactions pending bit sticks high
when there were pending transactions, we should wait and then continue
with our reset flow.
