LAN PHYs (other than LAN78xx which can generate test patterns itself), use the link partner (set to forced 10BASE-T) to transmit the signal to the device under test (DUT) and enable remote loopback on the DUT.
11 kwi 2017 · The intention of link training is to reduce the system-level challenge of tuning settings for every channel configuration (long, medium, short). By allowing the receiver to tell its link partner transmitter what settings to use, the goal is to eliminate the need for channel-specific tuning.
Several of the tests in Ethernet Compliance Testing can be performed using a Link Partner (especially in 10BASE-T). This is useful when the test requires the Device Under Test (DUT) to generate a pseudo-random sequence, but you do not have direct control over the DUT to generate this signal.
The PCS within the MAC can be reconfigured. Everything is configured at runtime. phylink acts as a single synchronization layer between the devices on the Ethernet link, maintaining a state machine. One of the goals is to ensure all elements of the link are configured using compatible modes.
negotiation with a Link Partner (LP) or require MAC-PHY handshaking. 10BASE-T and 10BASE-Te only send link pulses during IPG, unlike 100-Mbps and 1000-Mbps operation where there is a constant stream of IDLES between frames.
1 lis 2021 · Decides whether the adapter or link partner is designated as the master. The other device is designated as the slave. Changing the setting can improve link quality with certain link partners.
The Link Speed and Duplex setting lets you choose how the adapter sends and receives data packets over the network. In the default mode, an Intel network adapter using copper connections will attempt to auto-negotiate with its link partner to determine the best setting.
