patch 'net/pcap: set live interface as non-blocking' has been queued to stable release 23.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/30/24. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=84123ec794ad3a8c2796fe344030ce8fb9c32e67

Thanks.

[ upstream commit 60dd5a70035f447104d457aa338557fb58d5cb06 ]

The DPDK PMD's are supposed to be non-blocking and poll for packets.
Configure PCAP to do this on live interface.

Fixes: 4c173302c307 ("pcap: add new driver")
