[dpdk-dev] [PATCH 02/28] fm10k: add no-op pointer for VF request_tx_timestamp_mode

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.
