Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Lots of overlapping changes. Also on the net-next side
the XDP state management is handled more in the generic
layers so undo the 'net' nfp fix which isn't applicable
in net-next.

Include a necessary change by Jakub Kicinski, with log message:

====================
cls_bpf no longer takes care of offload tracking. Make sure
netdevsim performs necessary checks. This fixes a warning
caused by TC trying to remove a filter it has not added.

"What's a holiday weekend without some networking bug fixes? [1]

1) Fix some eBPF JIT bugs wrt. SKB pointers across helper function

10) Fix MTU limitng in GRE tunnel drivers, from Xin Long.

11) Fix stmmac timestamping bug due to mis-shifting of field. From
Fredrik Hallenberg.

12) Fix metrics match when deleting an ipv4 route. The kernel sets
some internal metrics bits which the user isn't going to set when
it makes the delete request. From Phil Sutter.

13) mvneta driver loop over RX queues limits on "txq_number" :-) Fix
from Yelena Krivosheev.

14) Fix double free and memory corruption in get_net_ns_by_id, from
Eric W. Biederman.

15) Flush ipv4 FIB tables in the reverse order. Some tables can share
their actual backing data, in particular this happens for the MAIN
and LOCAL tables. We have to kill the LOCAL table first, because
it uses MAIN's backing memory. Fix from Ido Schimmel.

16) Several eBPF verifier value tracking fixes, from Edward Cree, Jann
Horn, and Alexei Starovoitov.

17) Make changes to ipv6 autoflowlabel sysctl really propagate to
sockets, unless the socket has set the per-socket value
explicitly. From Shaohua Li.

18) Fix leaks and double callback invocations of zerocopy SKBs, from
Willem de Bruijn"

net: arc_emac: restart stalled EMAC

Under certain conditions EMAC stop reception of incoming packets and
continuously increment R_MISS register instead of saving data into
provided buffer. The commit implement workaround for such situation.
Then the stall detected EMAC will be restarted.

On device the stall looks like the device lost it's dynamic IP address.
ifconfig shows that interface error counter rapidly increments.
At the same time on the DHCP server we can see continues DHCP-requests
from device.

In real network stalls happen really rarely. To make them frequent the
broadcast storm[1] should be simulated. For simulation it is necessary
to make following connections:
1. connect radxarock to 1st port of switch
2. connect some PC to 2nd port of switch
3. connect two other free ports together using standard ethernet cable,
in order to make a switching loop.

After that, is necessary to make a broadcast storm. For example, running on
PC 'ping' to some IP address triggers ARP-request storm. After some
time (~10sec), EMAC on rk3188 will stall.

Observed and tested on rk3188 radxarock.
