[dpdk-dev] [PATCH v5 08/20] broadcom: localize mapping from eth_dev to pci

[Jan Blunck <jblunck@infradead.org>]

From: Stephen Hemminger <stephen@networkplumber.org>

Use existing information about pci and interrupt handle to minimize
the number of places that assume eth_dev contains pci_device
information.
