From: Bruce Richardson Date: Wed, 22 Oct 2014 10:55:45 +0000 (+0100) Subject: ixgbe: always perform vector Rx setup if vpmd enabled X-Git-Tag: spdx-start~10225 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=33e79bed3edc2bcf59;p=dpdk.git ixgbe: always perform vector Rx setup if vpmd enabled If the vector pmd option is turned on in the compile time config file, then always call the vector rxq setup, since we can now use the vector PMD for receiving jumbo frames that need chained mbufs, a.k.a scattered packets. Up till now, this function was not being called when receiving scattered packets, potentially leading to problems with mbufs not being properly initialized.
