From: Guinan Sun Date: Tue, 3 Dec 2019 16:59:27 +0000 (+0000) Subject: net/i40e: set fixed flag for exact link speed X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=dc73db27bb617a2755f27f243cf698e111d9e609;p=dpdk.git net/i40e: set fixed flag for exact link speed Setting exact link speed makes sense if auto-negotiation is disabled. Fixed flag is required to disable auto-negotiation.
