Subject: [PATCH] netfilter: nf_flow_table: fix offloaded connection timeout
corner case
The full teardown of offloaded flows is deferred to a gc work item,
however processing of packets by netfilter needs to happen immediately
after a teardown is requested, because the conntrack state needs to be
fixed up.
Since the IPS_OFFLOAD_BIT is still kept until the teardown is complete,
the netfilter conntrack gc can accidentally bump the timeout of a
connection where offload was just stopped, causing a conntrack entry
leak.
Fix this by moving the conntrack timeout bumping from conntrack core to
the nf_flow_offload and add a check to prevent bogus timeout bumps.

Subject: [PATCH] net: add support for threaded NAPI polling
For some drivers (especially 802.11 drivers), doing a lot of work in the NAPI
poll function does not perform well. Since NAPI poll is bound to the CPU it
was scheduled from, we can easily end up with a few very busy CPUs spending
most of their time in softirq/ksoftirqd and some idle ones.
Introduce threaded NAPI for such drivers based on a workqueue. The API is the
same except for using netif_threaded_napi_add instead of netif_napi_add.
In my tests with mt76 on MT7621 using threaded NAPI + a thread for tx scheduling
improves LAN->WLAN bridging throughput by 10-50%. Throughput without threaded
NAPI is wildly inconsistent, depending on the CPU that runs the tx scheduling
thread.
With threaded NAPI it seems stable and consistent (and higher than the best
results I got without it).
Based on a patch by Hillf Danton
