The default value for somaxconn is set in sysctl_core_net_init(), but this
function is not called when kernel is configured without CONFIG_SYSCTL.
This results in the kernel not being able to accept TCP connections,
because the backlog has zero size. Usually, the user ends up with:
"TCP: request_sock_TCP: Possible SYN flooding on port 7. Dropping request. Check SNMP counters."
If SYN cookies are not enabled the connection is rejected.
Before ef547f2ac1 (tcp: remove max_qlen_log), the effects were less
severe, because the backlog was always at least eight slots long.

Use wait_for_completion_timeout() instead of
wait_for_completion_interruptible_timeout() to avoid stray signals ruining
firmware update. Our timeout is only 300 msec so we are fine simply letting
it expire in case device misbehaves.

Some old touchpad FWs need to have interrupt cleared before issuing reset
command after updating firmware. We clear interrupt by attempting to read
full report from the controller, and discarding any data read.

net-next: stmmac: rework the speed selection
The current stmmac_adjust_link() part which handle speed have
some if (has_platform) code and my dwmac-sun8i will add more of them.
So we need to handle better speed selection.
Moreover the struct link member speed and port are hard to guess their
purpose. And their unique usage are to be combined for writing speed.
My first try was to create an adjust_link() in stmmac_ops but it duplicate some code
The current solution is to have direct value for 10/100/1000 and a mask for them.
The first 4 patchs fix some minor problem found in stmmac_adjust_link() and reported by Florian Fainelli in my previous serie.
The last patch is the real work.
This series is tested on cubieboard2 (dwmac1000) and opipc (dwmac-sun8i).
Changes since v3:
- Added the patch #4 "Convert old_link to bool" as suggested by Joe Perches
- Changed the speedmask
Changes since v2:
- Use true/false for new_state in patch #1

Moreover the struct link member speed and port are hard to guess their

So this patch replace speed/port by simpler
speed10/speed100/speed1000/speed_mask variables.
In dwmac4_core_init and dwmac1000_core_init, port/speed value was used
directly without using the struct link. This patch convert also their
usage to speedxxx.

Since 9b4437a5b8 ("geneve: Unify LWT and netdev handling.") fill_info
does not return UDP_ZERO_CSUM6_RX when using COLLECT_METADATA. This is
because it uses ip_tunnel_info_af() with the device level info, which is
not valid for COLLECT_METADATA.
Fix by checking for the presence of the actual sockets.
