From: Jan Blunck Date: Fri, 23 Dec 2016 15:58:06 +0000 (+0100) Subject: net/szedata2: localize handling of PCI resources X-Git-Tag: spdx-start~5221 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8acba705b119;p=dpdk.git net/szedata2: localize handling of PCI resources This changes the driver to handle the PCI resource directly instead of repeatedly going through eth_dev.
