If the PHY burst too many events, we will alloc a lot of events for the

erroneous state. Users can re-enable the PHY by

Different namespace application might require enable TCP Fast Open
feature independently of the host.
This patch series continues making more of the TCP Fast Open related
sysctl knobs be per net-namespace.
Reported-by: Luca BRUNO
Signed-off-by: Haishuang Yan
Change since v3:
* Split the patc
Different namespace application might require different tcp_fastopen_key
independently of the host.
Tested:
1. Container namespace:
# cat /proc/sys/net/ipv4/tcp_fastopen_key:
2817fff2-f803cf97-eadfd1f3-78c0992b
cookie key in tcp syn packets:
Fast Open Cookie
Kind: TCP Fast Open Cookie (34)
Different namespace application might require different time period in
second to disable Fastopen on active TCP sockets.
Tested:
Simulate following similar situation that the server's data gets dropped
after 3WHS.

This patch tries to add XDP_REDIRECT for virtio-net. The changes are
not complex as we could use exist XDP_TX helpers for most of the
work. The rest is passing the XDP_TX to NAPI handler for implementing
batching.

There's no need to add packet len average in the case of XDP_PASS
since it will be done soon after skb is created.

This patch set adds ls1012a MSI and PCIe support, including driver

driver patch has been applied, so only adds the PCIe device tree
nodes.

The ls1012a implement only 1 msi controller, and it is the same as
ls1043a.
