Fixed in Release: 20.32.1010 | |
2648336 | Description: Disabled the CNP counter “rp_cnp_ignored " (triggered by OOS (out-of-sequence)) when all ports are IB. Note: For mixed IB/ETH scenario, the behavior depends on the RoCE configuration, the counter on the IB port may still increase but will not affect the regular use. |
Keywords: CNP counter, IB | |
Discovered in Version: 20.30.1004 | |
Fixed in Release: 20.31.1014 | |

Discovered in Version: 20.30.1004 | |
Fixed in Release: 20.31.1014 | |
2621704 | Description: Fixed the resource number size (a 64 bit number) to avoid a scenario where it overwrote it with a 32 bit number and erased the high bits when de-allocating the resource number. In this scenario, when two resource numbers had identical low 32 bits, and because the high bits were cleared, it resulted in the same idx. Consequently, when two idxes were identical, then it freed the same idx twice. |
Keywords: Resource number size, free_4k page | |
Discovered in Version: 20.30.1004 | |
