Subject: [dpdk-dev] [PATCH 02/28] fm10k: add no-op pointer for VF request_tx_timestamp_mode
Date: Thu, 10 Sep 2015 12:38:11 +0800	[thread overview]
Message-ID: <1441859917-26475-3-git-send-email-xiao.w.wang@intel.com> (raw)
In-Reply-To: <1441859917-26475-1-git-send-email-xiao.w.wang@intel.com>

This patch resolves a bug in Linux where we called the
request_tx_timestamp_mode function that is undefined for VF. Implement a
no-op function that simply ensures that the mode is NONE, otherwise it
would fail with ERR_PARAM.
