Commit da3dedd9 ("[NET]: Make NAPI polling independent of struct
net_device objects.") changed the interface to NAPI polling.  Fix up
the ibm_emac driver so that it works with this new interface.  This is
actually a nice cleanup because ibm_emac is one of the drivers that
wants to have multiple NAPI structures for a single net_device.

Tested with the internal MAC of a PowerPC 440SPe SoC with an AMCC
'Yucca' evaluation board.

Problem description by Daniel Drake <dsd@gentoo.org>:

"This sequence of events causes loss of connectivity:

<plug in>
<associate as normal in managed mode>
ifconfig eth7 down
iwconfig eth7 mode monitor
ifconfig eth7 up
ifconfig eth7 down
iwconfig eth7 mode managed
<associate as normal>

At this point you are associated but TX does not work. This is because
the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit."

The problem is caused by ieee80211_if_set_type checking for a non-zero
hard_start_xmit pointer value in order to avoid changing that value for
master devices.  The fix is to make that check more explicitly linked to
master devices rather than simply checking if the value has been
previously set.

Some versions of gcc replace strstr() calls with a single-character `needle'
parameter by strchr() behind our back. This causes a link error if strchr() is
defined as an inline function in <asm/string.h> (e.g. on m68k):

| drivers/built-in.o: In function `libertas_parse_chan':
| linux/drivers/net/wireless/libertas/debugfs.c:209: undefined reference to `strchr'
| drivers/built-in.o: In function `libertas_parse_ssid':
| linux/drivers/net/wireless/libertas/debugfs.c:260: undefined reference to `strchr'

Avoid this by explicitly calling strchr() instead.

Also include <linux/string.h>, because this file calls lots of str*() routines.

Reorganize configuration handling by creating a extra
structure which contains precalculated values based
on the mac80211 values which are usefull for all
individual drivers.

This also fixes the preamble configuration problem,
up untill now preamble was never configured since
by default the rate->val value was used when changing
the mode.
Now rate->val will only be used to set the basic rate mask.
The preamble configuration will now be done correctly
through the erp_ie_changed callback function.

As reported by Modestas Vainius, enabling rkfill in 1 driver and
disabling it in a second could cause a NULL pointer exception when
the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.

Furthermore, rfkill expects the timeout as a value in milliseconds
instead of jiffies. Also increase the timeout to a second,
since this 250ms would be overkill.

Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
for devices which do not support the hardware button
while rfkill is enabled in the driver.

To remidy this we should inverse the flag and its meaning,
rename the flag to DEVICE_DISABLED_RADIO_HW this means that
by default the radio is enabled by the hardware button (if present)
and can only be disabled explicitely.

We shouldn't use changed_flags when configuring the packet filter,
we work directly with the total_flags which is safe enough since
we already check if something has changed after we applied our
packet filtering flag rules.
Also make sure that when the packet filter is scheduled, the
rt2x00dev->interface.filter is cleared to make sure the drivers
will update the packet filter instead of failing at the check:
*total_flags == rt2x00dev->interface.filter
