| 4757785 / 4741625 | Description: Fixed an issue by introducing a new PCIe channel estimation algorithm, improving performance across a wide range of channel conditions. |
| Keywords: PCIe |
| Discovered in Version: 28.43.3608 |
| Fixed in Release: 28.43.4100 |
| 4527750 / 4400949 | Description: Fixed an issue where the MCTP context was incorrectly cleared when a new message arrived over a different transport. |
| Keywords: MCTP |
| Discovered in Version: 28.43.3608 |
| Fixed in Release: 28.43.4100 |
| 4774378 / 3921355 | Description: Fixed a deadlock seen during stress traffic with small packets and modify actions, which could hang the SoC (e.g., testpmd with three SFs and hardware offload disabled). |
| Keywords: Firmware deadlock, small packets |
| Discovered in Version: 28.43.3608 |
| Fixed in Release: 28.43.4100 |
| 4780433 / 4450570 | Description: Fixed an issue where the root complex sent MCTP-over-PCI messages before a BDF was assigned, causing responses to be sent with BDF 0. The fix ensures that MCTP messages routed by ID are ignored until a valid BDF is assigned. |
| Keywords: MCTP-over-PCI, BDF, MCTP messages |
| Discovered in Version: 28.43.3608 |
| Fixed in Release: 28.43.4100 |
| 4778182 / 4375264 | Description: Fixed an issue where querying high I²C address EEPROM pages for SFP modules incorrectly returned data from the low address page instead. |
| Keywords: I²C address, EEPROM pages, SFP modules |
| Discovered in Version: 28.43.3608 |
| Fixed in Release: 28.43.4100 |
| 4778175 / 4362705 | Description: Implemented additional strict validation of incoming NC-SI packets by verifying the payload length parameter to improve robustness and prevent malformed packet handling. |
| Keywords: NC-SI |
| Discovered in Version: 28.43.3608 |
| Fixed in Release: 28.43.4100 |
| 4727304 / 4718947 | Description: Fixed an issue in the steering definers used for LAG with IPv6 traffic. |
| Keywords: LAG, IPv6 traffic, steering |
| Discovered in Version: 28.43.3608 |
| Fixed in Release: 28.43.4100 |
| 4370695 / 4656353 / 4739817 | Description: Fixed a corner case during warm reboot that could cause some TX lane elastic buffers to lose synchronization during link training. |
| Keywords: TX lane elastic buffers |
| Discovered in Version: 28.43.2566 |
| Fixed in Release: 28.43.4100 |
| 4508525 / 4480427 | Description: Fixed incorrect calculation of start address and mode for the CQE buffer in DPA CQ, which could cause CQEs to be written to the wrong address when the buffer is not 4K-aligned and spans a second page boundary. |
| Keywords: CQ, CQE Buffer, DPA |
| Discovered in Version: 28.43.2566 |
| Fixed in Release: 28.43.4100 |
