net/iavf: negotiate PTP before reporting Rx timestamping
The iavf driver has support for hardware Rx timestamps since commit
b5cd735132f6 ("net/iavf: enable Rx timestamp on flex descriptor").
To enable this, the VF must first negotiate PTP capabilities with the PF
by sending the VIRTCHNL_OP_1588_PTP_GET_CAPS command, with the requested
capabilities. The PF will respond with the actually supported subset of
capabilities.
The PF may not actually enable Rx timestamping, even if it reports the
overall PTP capability support. If this happens, the iavf driver logic
will incorrectly report that Rx timestamps can be enabled despite being
rejected by the PF.
This should be unlikely in practice, as most PFs which support the
VIRTCHNL_VF_CAP_PTP will support Rx timestamping. However, there are
some cases where this may not be true. In particular, there is an
unfortunate issue with some versions of the ice PF using a different
structure layout that prevents the PF from enabling Rx timestamping.
To prevent this, the DPDK driver should check the capabilities and
confirm that the PF did enable Rx timestamping, instead of assuming it
will be enabled by all PFs that support the VIRTCHNL_CAP_PTP feature.
This prevents the DPDK application from attempting to enable Rx
timestamps when the PF will not support it.
Currently, the DPDK driver only negotiates PTP capabilities when the
device is started. First, check the capabilities during iavf_dev_init()
so that the iavf_dev_info_get() function has the required knowledge.
Then, only set RTE_ETH_RX_OFFLOAD_TIMESTAMP when the PF has informed
that it enabled support.
Continue to re-check the PTP capabilities in iavf_dev_start(), as it is
important to renegotiate after device reset.
