Since 'rtlpriv->cfg->ops->fill_tx_cmddesc()' is always called
with 'firstseg' and 'lastseg' set to 1 (and the latter is
never actually used), all of the relevant chip-specific
routines may be simplified. Compile tested only.

Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.
With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.
To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.
For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.
For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.
Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.
Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

In this step, the read/write routines for the descriptors are converted
to use __le32 quantities, thus a lot of casts can be removed. Callback
routines still use the 8-bit arrays, but these are changed within the
specified routine.

As a first step in the conversion, the macros that set the RX and TX
descriptors are converted to static inline routines, and the names are
changed from upper to lower case. To minimize the changes in a given
step, the input descriptor information is left as as a byte array
(u8 *), even though it should be a little-endian word array (__le32 *).
That will be changed in the next patch.
Several places where checkpatch.pl complains about a space after a cast
and other warnings are fixed.

This driver uses a set of local macros to manipulate the RX and TX
descriptors, which are all little-endian quantities. These macros
are replaced by the bitfield macros le32p_replace_bits() and
le32_get_bits(). In several places, the macros operated on an entire
32-bit word. In these cases, a direct read or replacement is used.

Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.
