Add support for netdev-genl, allowing users to query IRQ, NAPI, and queue information. After this patch is applied, note the IRQ assigned to my NIC: $ cat /proc/interrupts | grep enp0s8 | cut -f1 --delimiter=':' 18 Note the output from the cli: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump napi-get --json='{"ifindex": 2}' [{'id': 513, 'ifindex': 2, 'irq': 18}] This device supports only 1 rx and 1 tx queue, so querying that: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump queue-get --json='{"ifindex": 2}' [{'id': 0, 'ifindex': 2, 'napi-id': 513, 'type': 'rx'}, {'id': 0, 'ifindex': 2, 'napi-id': 513, 'type': 'tx'}] Signed-off-by: Joe Damato <jdamato@fastly.com> --- drivers/net/ethernet/intel/e1000/e1000_main.c | 5 +++++ 1 file changed, 5 insertions(+)
