Subject: [net-next 2/2] ena: Link queues to NAPIs
Date: Mon, 30 Sep 2024 19:56:13 +0000 [thread overview]
Message-ID: <20240930195617.37369-3-jdamato@fastly.com> (raw)
In-Reply-To: <20240930195617.37369-1-jdamato@fastly.com>
Link queues to NAPIs using the netdev-genl API so this information is
queryable.
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
--dump queue-get --json='{"ifindex": 2}'
