Subject: [dpdk-dev] [PATCH 02/16] fm10k: add no-op pointer for VF request_tx_timestamp_mode
Date: Mon, 27 Jul 2015 16:42:25 +0800 [thread overview]
Message-ID: <1437986559-31016-2-git-send-email-xiao.w.wang@intel.com> (raw)
In-Reply-To: <1437986559-31016-1-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.
