## Symptoms

- High rate of rx discards/errors on interfaces after reboot when Multi-Queue (MQ) is configured.

For example:  

```

[Expert@15600:0]#cpmq get -v

 Active mlx5_core interfaces:
 eth2-01 [Off] 
 eth2-02 [Off]  
 
 Active ixgbe interfaces: 
 eth3-01 [On] 
 eth3-02 [On]  
 
 Active igb interfaces: 
 Mgmt [Off] 
 Sync [Off] 
 eth1-01 [Off]  
 
 The rx_num for ixgbe is: 4 (default)  
 
 multi-queue affinity for ixgbe interfaces:
