Task 5.5: Integrate utility functions and supplementary features into the driver #37

Open CraigOpie opened 1 year ago

Description: Integrate the implemented logging, configuration, error handling, and statistics functions into the virtual network driver. Ensure that these features work seamlessly with the core functionality and do not introduce new issues.

Duration: 0.5 day

Things to consider for this task and all of which are dependent on time management and deadlines:

  1. Device statistics: The driver currently only tracks basic statistics like transmitted and received packets and bytes. We might want to expand this to include more detailed statistics such as packet errors, collisions, or other hardware-specific counters.

  2. Interrupt handling: Real hardware devices usually use interrupts to signal events like the arrival of a new packet or the completion of a transmission. Our driver could simulate interrupts by adding an interrupt handler and using a timer or a workqueue to trigger the interrupt at a specific interval.

  3. Link status: In our current driver, the link is always considered up. We might want to add the ability to simulate a link going up and down.

  4. Promiscuous mode: Real network devices can be set to promiscuous mode, where they receive all packets on the network, not just those destined for their MAC address. We might want to add support for this mode to our virtual driver.

  5. Multicast filtering: Real network devices can filter multicast traffic based on a set of multicast addresses. We could add support for multicast filtering to our virtual driver.

  6. VLAN support: Real network devices often support VLAN tagging and filtering. We might want to add support for this feature to our virtual driver.

  7. Offloading: Some network devices support offloading features such as TCP/IP checksum calculation, segmentation, and large receive offload. We could add support for these features to our virtual driver.

  8. QoS support: Real network devices often support Quality of Service (QoS) features such as priority-based scheduling, rate limiting, or traffic shaping. We might want to add support for these features to our virtual driver.

  9. Custom IOCTLs: We have a placeholder in our code for handling custom IOCTLs, but no actual IOCTLs are defined. We could add IOCTLs for specific hardware features, or for controlling the behavior of our virtual driver.
