Subject: [dpdk-dev] [PATCH 09/14] lib/ether: generalize attach/detach of devices
Date: Mon,  4 Jan 2016 21:08:21 +0100	[thread overview]
Message-ID: <1451938106-12145-10-git-send-email-viktorin@rehivetech.com> (raw)
In-Reply-To: <1451938106-12145-1-git-send-email-viktorin@rehivetech.com>

Make the attach and detach functions independent on the PCI infra. Mostly, this
means to utilize the rte_bus_addr instead of rte_pci_addr.
