[IPV4]: Remove unsupported DNAT (RTCF_NAT and RTCF_NAT) in IPV4
- The DNAT (Destination NAT) is not implemented in IPV4.
- This patch remove the code which checks these flags
in net/ipv4/arp.c and net/ipv4/route.c.
The RTCF_NAT and RTCF_NAT should stay in the header (linux/in_route.h)

[TIPC]: Use tipc_port_unlock
The file net/tipc/port.c takes a lock using the function tipc_port_lock and
then releases the lock sometimes using tipc_port_unlock and sometimes using
spin_unlock_bh(p_ptr->publ.lock). tipc_port_unlock simply does the
spin_unlock_bh, but it seems cleaner to use it everywhere.
The problem was fixed using the following semantic patch.

rc80211_pid should respect fixed rates.
I would argue that mac80211 should handle fixed rates outside the rate
control code, which would also allow them to take effect immediately
instead of during the rate control callback, but this is pretty close
to correct.

mac80211: better rate control algorithm selection
This patch changes mac80211's Kconfig/Makefile to:
* select between the PID and the SIMPLE rate control
algorithm as default
* always allow tri-state for the rate control algorithms,
building those that are selected 'y' into the mac80211
module (if that is a module, otherwise all into the kernel)
* force the default rate control algorithm to be built into
mac80211
It also makes both rate control algorithms proper modules again
with MODULE_LICENSE etc.
Only if EMBEDDED is the user allowed to select "NONE" as default
which will cause no algorithm to be selected, this will work
only when the driver brings one itself (e.g. iwlwifi drivers).

This issue occurs when the sequence of the internal MPDUs is not in the
