From: Jeff Guo Date: Sat, 8 Apr 2017 05:56:40 +0000 (+0800) Subject: app: enable HW CRC strip by default X-Git-Tag: spdx-start~3681 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=79dd163fcaac74006ab607b6c0d1baacc9c40d92;p=dpdk.git app: enable HW CRC strip by default Since VF can not disable/enable HW CRC strip for non-DPDK PF drivers, and kernel driver almost default enable that feature, if disable it in app's rxmode, VF driver will report the VF launch failure. So this patch default to enable HW CRC strip to let VF launch successful.
