- **Interrupts**
- Only one interrupt per vNIC interface should be configured in the UCS
+ At least one interrupt per vNIC interface should be configured in the UCS
manager regardless of the number receive/transmit queues. The ENIC PMD
uses this interrupt to get information about link status and errors
in the fast path.
+ In addition to the interrupt for link status and errors, when using Rx queue
+ interrupts, increase the number of configured interrupts so that there is at
+ least one interrupt for each Rx queue. For example, if the app uses 3 Rx
+ queues and wants to use per-queue interrupts, configure 4 (3 + 1) interrupts.
