Cover letter [PATCH rdma-next 0/5] Dropples RQ
Hi Doug,
Quoted 1 line
From Maor:
---
This series adding support to avoid RAW ethernet packet drops.
When packets received and there are no receive WQEs, then the packets are dropped. In certain scenarios it may be preferred to configure the device to avoid such packet drops, assuming the posting of WQEs will resume shortly.
Under such configuration, when a packet is received for a WQ with no receive WQEs, the packet processing is delayed until receive WQEs are posted.
If receive WQEs are still not posted after a device configured time, the packet is dropped.
To enable this delay drop feature on a WQ, the user should set the IB_WQ_FLAGS_DELAY_DROP flag on creation.
