This is particularly useful for epoll-based busy polling apps which rely on having access to the NAPI ID. I've tested these commits on an EC2 instance with an ENA NIC configured and have included test output in the commit messages for each patch showing how to query the information. I noted in the implementation that the driver requests an IRQ for management purposes which does not have an associated NAPI. I tried to take this into account in patch 1, but would appreciate if ENA maintainers can verify I did this correctly. v1: https://lore.kernel.org/all/20240930195617.37369-1-jdamato@fastly.com/ ==================== Link: https://patch.msgid.link/20241002001331.65444-1-jdamato@fastly.com Signed-off-by: Jakub Kicinski --- 35d8471e242d93ae5ef76580df2ebb92ce35e144
