Publication number: 20240064216Abstract: Examples described herein relate to a network interface comprising physical medium dependent (PMD) circuitry, the PMD circuitry to during link training of at least one lane consistent with IEEE 802.3, exit to TIME_OUT state during TRAIN_LOCAL state based on consideration of expiration of a wait timer, loss of local_tf_lock state, and loss of remote_tf_lock state. In some examples, during link training for at least one lane consistent with IEEE 802.3, the PMD circuitry is to exit to TIME_OUT state during TRAIN_REMOTE state based on consideration of expiration of a wait timer, loss of local_tf_lock state, and loss of remote_tf_lock state. In some examples, link training consistent with IEEE 802.3 comprises performance of the PMD control function in Section 162.8.11 of IEEE 802.3ck.Type: ApplicationFiled: September 28, 2023Publication date: February 22, 2024Applicant: Intel CorporationInventor: Kent C.

Patent number: 11424901Abstract: Loop timing is performed in a Reconciliation Sublayer (RS) so that the transmit clock frequency can be adjusted to be equal to the receive clock frequency for the entire PHY (including the physical coding sublayer (PCS)). One of two partners is selected to be the timing Slave to the other. If only one partner is capable of loop timing, that partner becomes the Slave. If both partners are capable of loop timing, symmetry breaking can be used to determine which partner should become Slave.Type: GrantFiled: October 17, 2019Date of Patent: August 23, 2022Assignee: Intel CorporationInventors: Adee Ofir Ran, Kent C.

Patent number: 11277308Abstract: Technologies for autonegotiation of communications operational modes over copper cable include a network port logic having a communication link coupled to a remote link partner. The network port logic may start an autonegotiation protocol upon reset, when the link is broken, or upon manual renegotiation. The network port logic transmits an autonegotiation page to the remote link partner that indicates single-lane communications ability over copper cable. The network port logic receives an autonegotiation page from the link partner indicating single-lane communications ability over copper cable. If the network port logic and link partner have a common single-lane communication ability, the link may be activated. The autonegotiation pages may be base pages or next pages. The single-lane communication ability may be indicated by one or more bits of the autonegotiation pages. The link may be established at 1 gigabit or 10 gigabits per second. Other embodiments are described and claimed.Type: GrantFiled: April 13, 2020Date of Patent: March 15, 2022Assignee: Intel CorporationInventors: Kent C. Lusted, Adee O. Ran

Patent number: 10601737Abstract: Methods and apparatus for register Read and Write operations over Auto Negotiation Next Pages. Register Reads and Writes are implemented using sequences of Auto Negotiation (AN) Next Page messages. The embodiments define mechanisms to use AN Next Pages to carry write and read instructions. It defines a bi-directional communication mechanism to allow writes to be confirmed and read data to be returned to the requestor. Sequences of several AN Next Pages are used to assemble full address and data fields, when necessary. Two link partners (endpoints or an endpoint and an intermediate partner) exchange AN Next Pages with address and data information. The method uses a unique device address assigned to each device discovered in the serial chain to enable write and read operations to specific devices.Type: GrantFiled: August 30, 2016Date of Patent: March 24, 2020Assignee: Intel CorporationInventors: K.

Patent number: 10164912Abstract: Methods and apparatus for Ethernet auto-negotiation (AN) with parallel detect for 10G DAC or other non-auto-negotiated modes. AN base pages are transmitted from an Ethernet apparatus to advertise the ability to support at least one Institute of Electrical and Electronics Engineers (IEEE) 802.3 Ethernet specification supporting AN. A receiver and associated processing circuitry is configured to perform two detection modes in parallel, including a first detection mode that looks for a valid signal transmitted from an Ethernet link peer that does not support AN and a second detection mode looking for AN pages from an IEEE 802.3 Ethernet link peer that supports AN. If the link peer does not support AN, an Ethernet link is set up to use signaling in accordance with the Ethernet specification that does not support AN. If the link peer supports AN, an Ethernet link is set up using a corresponding IEEE 802.3 Ethernet link supporting AN. Supported non-AN Ethernet links include 10G DAC links.Type: GrantFiled: July 25, 2016Date of Patent: December 25, 2018Assignee: Intel CorporationInventors: Adee O. Ran, David L. Chalupsky, Kevan A.

Patent number: 10007634Abstract: Methods for implementing mini-mezzanine Open Compute Project (OCP) plug-and-play Network PHY Cards and associated apparatus. In accordance with one aspect, the MAC (Media Access Channel) and PHY (Physical) layer functions in one or more communication protocol stacks are split between a MAC block in a Platform Controller Hub (PCH) or processor SoC and a PHY card installed in a mezzanine slot of a platform and including one or more ports. During platform initialization operations, configuration parameters are read from the PHY card including a PHY card ID, and a corresponding configuration script is selected and executed to configure the PHY card for use in the platform. The configuration parameters are also used to enumerate PCIe devices associated with physical functions and ports supported by the PHY card.Type: GrantFiled: December 7, 2015Date of Patent: June 26, 2018Assignee: Intel CorporationInventors: Scott P.
