From: Matan Barak Date: Wed, 6 Nov 2013 22:21:50 +0000 (+0100) Subject: IB/core: Re-enable create_flow/destroy_flow uverbs X-Git-Tag: accepted/tizen/common/20141203.182822~1080^2^3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=69ad5da41b4ed94aef31d4111a3442cfd73ce570;p=platform%2Fkernel%2Flinux-arm64.git IB/core: Re-enable create_flow/destroy_flow uverbs This commit reverts commit 7afbddfae993 ("IB/core: Temporarily disable create_flow/destroy_flow uverbs"). Since the uverbs extensions functionality was experimental for v3.12, this patch re-enables the support for them and flow-steering for v3.13.
