In the related art, an ethernet hardmac may be disposed inside each network card hardware, and the ethernet is a computer local area network technology, which specifies the content of the connection line including the physical layer, the electrical signal and the medium access layer protocol, and is the most commonly used local area network technology.

The Ethernet controller is a hard core IP provided by Intel and can be instantiated in engineering for direct use, and the nios soft core processor is a configurable processor which is developed based on C language and optimized by programmable logic. A second device 405 (e.g., a switch) may be connected (including both physically and logically) to network card 402 through ethernet controller 403. The second device can be physically connected with the network card in advance through a cable and an interface; the network card then configures the connection interface so that the second device negotiates a link with the network card logic.

In some embodiments, as shown in fig. 4, a network card may be disposed on a first device (e.g., a server), the network card may include an interface controller (e.g., an ethernet interface controller) and a soft-core processor (e.g., a nios soft-core processor), and a second device may be physically and logically connected to the network card through the interface controller.
In some embodiments, before the following network card configuration method is performed, the corresponding configuration parameter sets of each device (e.g., a switch) that needs to be connected to the network card under different cable types (which may include, for example, an optical fiber type cable and a copper type cable) may be written into the network card through a read-write technology.
Referring to fig. 11, the network card configuration method may include the following steps.
S1101, electrifying the intelligent network card, integrally resetting the Ethernet controller or detecting hot plug of the cable.
Under the three conditions that the first equipment (such as a server) is started, so that the intelligent network card is electrified, the cable module DAC (copper cable)/AOC (optical fiber) is plugged and pulled or the interface controller is reset, the nios soft-core processor starts to work.
S1102, judging whether the cable type is an optical fiber type or a copper type.
The nios soft core processor reads relevant register parameters by controlling the Ethernet controller to detect the quality type of a cable connected with the network card and determine whether the cable is a DAC (copper cable) or an AOC (optical fiber).
In some embodiments, if it is determined that the cable is an optical fiber cable, steps S1103 to S1109 are performed; if the cable is a copper cable, step S1110 to step S1116 are performed.
When configuring An interface corresponding to the optical fiber cable, the configuration parameter group A1 to An may be traversed to configure the interface until a configuration parameter group that enables the logical link between the network card and the second device to be successful is found.
Referring to fig. 11, steps S1103 to S1109 may include the following processes.
S1103, configure the parameter group A1.
If it is detected that it is an AOC cable, configuration of the already prepared parameter set A1 is started.
S1104, the switching of the rate and the error correction configuration parameter support is carried out, and whether the link is successful is judged.
And after the parameter configuration is finished, switching the cable rate (25G/10G) and FEC (code error correction) related configuration, exiting the loop if the link with the current second device (such as a switch) is successful, otherwise, continuing to execute the step S1105.
S1105, configure parameter set A2.
Similarly, if the connection with the current second device via the configuration parameter set A2 is successful, the loop can be exited, otherwise, the next round of parameter set configuration is continued.
S1106, performs rate and error correction configuration parameter support switching, and determines whether the link is successful.
S1107, performs rate and error correction configuration parameter support switching, and determines whether the link is successful.
S1108, a parameter group An is configured.
S1109, carrying out rate and error correction configuration parameter support switching, and judging whether the link is successful.
It will be appreciated that since all of the second devices have been previously docked, it is inevitable that the linking will succeed on some set of parameters therein.
In some embodiments, the configuration parameter set corresponding to the copper cable may include configuration parameter sets B1 to Bn, and when an interface corresponding to the copper cable is configured, the interface may be configured by traversing the configuration parameter sets B1 to Bn until a configuration parameter set that enables the network card and the second device to be successfully linked is found.
Referring to fig. 11, steps S1110 to S1116 may include the following processes.
S1110, configure parameter set B1.
Similarly, if the DAC cable is detected, the already prepared parameter set B1 is configured, and the subsequent configuration process is similar to the above AOC cable, and will not be described here again.
S1111, carrying out rate and error correction configuration parameter support switching, and judging whether the link is successful.
S1112, configuring parameter group B2
S1113, the support of the rate and the error correction configuration parameters is switched, and whether the link is successful is judged.
S1114 performs rate and error correction configuration parameter support switching, and determines whether the link is successful.
And S1115, configuring the parameter group Bn.
S1116, perform rate and error correction configuration parameter support switching, and determine whether the link is successful.
In some embodiments, if a second device type is newly added in the middle of the process, and all parameter sets corresponding to the second device and the cable media types fail to be linked, a configuration parameter set corresponding to the second device needs to be obtained, and the configuration parameter set is written into the network card by encoding, and the technical solution corresponding to the embodiment shown in fig. 11 is executed again.
The technical scheme provided by the embodiment designs an improved method aiming at the problem of insufficient compatibility of the Ethernet interface in the current intelligent network card. The method adds a nios soft core processor in the hardware, and configures a plurality of groups of parameter configurations required to be used by the Ethernet controller according to a certain flow, thereby improving the compatibility of the intelligent network card port and the switch auto-negotiation.
