netdevsim: Mark NAPI ID on skb in nsim_rcv
[ Upstream commit f71c549b26a33fd62f1e9c7deeba738bfc73fbfc ]
Previously, nsim_rcv was not marking the NAPI ID on the skb, leading to
applications seeing a napi ID of 0 when using SO_INCOMING_NAPI_ID.
To add to the userland confusion, netlink appears to correctly report
the NAPI IDs for netdevsim queues but the resulting file descriptor from
a call to accept() was reporting a NAPI ID of 0.
