This prevents PHY not found types of errors for PHY drivers that are
probed after the Ethernet driver is probed, because the ifconfig UP is
done from userspace after all drivers have been probed.
Also avoid the cvmx-helper-board.c PHY code if a real PHY driver is
present, this allows a bootloader supplied device tree to specify the
PHY information rather than having to modify the code for each
different board.

staging: rtl8192u: remove checks for CONFIG_IEEE80211_CRYPT_TKIP
Ever since rtl8192u was added as a staging driver in v2.6.33 it contained
checks for CONFIG_IEEE80211_CRYPT_TKIP. But the Kconfig symbol
IEEE80211_CRYPT_TKIP was renamed to LIB80211_CRYPT_TKIP in v2.6.29. So
these checks have always evaluated to false. And these checks were rather
odd to begin with, since rtl8192u comes with its own ieee80211 stack,
which has support for TKIP built in.
Now the safe and easy thing to do here would be to remove these checks
and the code they hide. But it turns out that with some minor cleanup
the code currently hidden behind these checks builds cleanly. And by
building it we allow the people actually running this code to test
whether it is any good.
That minor cleanup is needed because ieee80211_encrypt_fragment()
accesses struct sk_buff's data member as if it is a struct
ieee80211_hdr. It's not. See, in ieee80211_xmit() a struct
ieee80211_hdr_3addrqos is skb_put() into the sk_buff with which
ieee80211_encrypt_fragment() will be called. So switch from
ieee80211_hdr to ieee80211_hdr_3addrqos here.

The ni_atmio and ni_mio_cs drivers use identical code to handle the

STC registers is also disabled due to a difference on the 611x devices.

This macro is used to create the private data structure that is used by
the ni_atmio, ni_mio_cs, and ni_pcimio drivers. These drivers all include
the ni_mio_common.c source to provide most of the driver functionality.
The only driver specific information needed to convert the macro into a
proper struct definition is the MAX_N_CALDACS define. This define is used
to size a couple array members in the struct. The ni_atmio and ni_mio_cs
drivers both define MAX_N_CALDACS as 32. The ni_pcimio driver defines it
as (16+16+2). The ni_mio_common file only uses this define to sanity check
that the struct members are large enough for the number of channels in
the calibration subdevice.
Move the MAX_N_CALDACS define to ni_stc.h and set it to the largest number
of caldacs (34).
The ni_atmio and ni_mio_cs drivers also add one additional member to the
private data struct before using the NI_PRIVATE_COMMON macro.
For the ni_atmio driver, the struct pnp_dev pointer can be saved in the
comedi_device as the 'hw_dev'. The (*detach) of this driver can then use
to_pnp_dev() to get it back when detaching the pnp device.
In the ni_mio_cs driver, the struct pcmia_device pointer is not used so
it can simply be removed.
The NI_PRIVATE_COMMON macro can then be converted into a proper struct
definition.
