mac80211: let flush() drop packets when possible
This reverts commit 4e6c48e098.
In order to change the usage of U-APSD on the fly later,
move the enabling condition into a new function that is
called when authenticated.
This allows the module parameter to become writable, it
won't take effect immediately but at least on the next
association the new value will be used.

If the firmware sends spontaneous DTS notfications with the
temperature (indicated in a TLV), we can ignore the temperature we get
in the RX statistics notifications. This prevents potentially
handling the same temperature change twice. It also ignores
notifications with temperature equal to 0 that happens from time to
time.

When we want to trigger an NMI in the device, we need to set
bit 7 and not bit 0. However, older firmwares don't register
to the interrupt issued by bit 7. Use bit 7 first so that
the correct interrupt will be issued hoping that the firmware
will react. To be on the safe side, set bit 0 in case the
firmware didn't register to the proper interrupt.

Fragmented scan should be applied for all channels, passive and active.
When scanning on passive channels the firmware uses frag_passive_dwell
to define the maximum continuous scan time before returning to the
operating channel. On active channels max_out_time is the parameter
used by the firmware to define the maximum time allowed out of the
operating channel. Since active channels' scan should also be fragmented
set max_out_time equal to frag_passive_dwell.
In addition:
- Set max_out_time and suspend_time if the firmware doesn't support
fragmented scan to avoid unexpected behavior.
- Adjust max_out_time for second level of scan precedence.

The driver connects and disconnects the PHY device whenever the

set_settings and nway_reset operations will dereference a null
or dangling pointer if called while it is down.
I think it would be preferable to keep the PHY connected, but there
may be good reasons not to.
As an immediate fix for this bug:
- Set the phydev pointer to NULL after disconnecting the PHY
- Change those three operations to return -ENODEV while the PHY is
not connected

- Remove the unlikely() from the TSU functions that we may safely
call for chips without a TSU
- Make setting of the MCT flag conditional on the tsu capability flag
- Rename sh_eth_set_multicast_list() to sh_eth_set_rx_mode() and plumb
it into both net_device_ops structures
- Remove the previously-unreachable branch in sh_eth_rx_mode() that

This patch add support for 1G Ethernet driver based on Keystone
NetCP hardware. The gigabit Ethernet (GbE) switch subsystem is one of the main
components of the network coprocessor (NETCP) peripheral. The purpose of the
gigabit Ethernet switch subsystem in the NETCP is to provide an interface to
transfer data between the host device and another connected device in
compliance with the Ethernet protocol. GbE consists of 5 port Ethernet Switch
module, 4 Serial Gigabit Media Independent Interface (SGMII) modules, MDIO
module and SerDes.
Driver for 5 port GbE switch and SGMII module is added in this patch. These
hardware modules along with netcp core driver provides Network driver functions
for 1G Ethernet.
