Bug ID: 1865
Summary: net/pcap: support for multiple queues is broken
Product: DPDK
Version: 25.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: major
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When use using pcap PMD the driver advertises support for 16 queues.
But this is not correct. Each queue is a separate instance of pcap handle which
is a then handled as separate file descriptor.
The result is that on transmit each queue overwrites the other in the file. And
can result in truncated or corrupt file. On receive each queue reads all the
packets in the file, there is no RSS or distribution.
Driver should just not report multi-queue or it needs to do locking.
