PTP feature is supported if the VIRTCHNL2_CAP_PTP is negotiated during the
capabilities recognition. Initial PTP support includes PTP initialization
and registration of the clock.

Tx timestamp capabilities are negotiated for the uplink Vport.
Driver receives information about the number of available Tx timestamp
latches, the size of Tx timestamp value and the set of indexes used
for Tx timestamping.

The current code in ixgbe_82599 checks the SFP Ethernet compliance code
against IXGBE_SFF_BASEBX10_CAPABLE to determine if an SFP module supports
1GB BASE-BX. According to SFF-8472 (section 5.4 Transceiver Compliance
Codes), the BASE-BX10 bit is defined as bit 6, which corresponds to a

This patch series introduces support for Precision Time Protocol (PTP) to
Intel(R) Infrastructure Data Path Function (IDPF) driver. PTP feature is
supported when the PTP capability is negotiated with the Control
Plane (CP). IDPF creates a PTP clock and sets a set of supported
functions.
During the
PTP clock configuration operations - set time, adjust time and adjust
frequency are required to control the clock and mantain synchronization
process.
Extend get PTP capabilities function to request for the clock adjustments
and add functions to enable these actions using dedicated virtchnl
messag
Add Rx timestamp function when the Rx timestamp value is read directly
from the Rx descriptor. Add supported Rx timestamp modes.

SFF-8472 (section 5.4 Transceiver Compliance Codes) defines bit 6 as

The current value in the source code is 0x64, which appears to be a

PTP capabilities are negotiated using virtchnl commands. There are two
available modes of the PTP support: direct and mailbox. When the direct

If the CONFIG_INFINIBAND_IRDMA symbol is not enabled as a module or a
built-in, then don't let the driver reserve resources for RDMA.
Do this by avoiding enabling the capability when scanning hardware
capabilities.
