[PATCH 00/10] staging: rtl8723bs: replace private 802.11 header macros with generic helpers

[Rishik Yechuri]

The rtl8723bs driver has its own set of macros and inline functions in
wifi.h for working with 802.11 frame headers. They access the header
through hardcoded byte offsets and pointer casts, and they duplicate
struct ieee80211_hdr and the helpers in <linux/ieee80211.h> that
mac80211, cfg80211 and other wireless drivers already use.

This series switches the driver over to the generic versions and
deletes the private ones from wifi.h. Each patch converts one group of
macros and removes their definitions once nothing uses them anymore,
so the driver builds after every patch.

  Patches 1 to 3 convert header address access and the Frame Control
  flag checks and updates.

  Patches 4 and 5 convert the frame type and subtype checks. Single
  comparisons use the ieee80211_is_*() helpers, and switch statements
  mask frame_control with IEEE80211_FCTL_* and use IEEE80211_STYPE_*
  case labels, the same way mac80211 does.

  Patch 6 removes an unused struct member. Its initialisers were the
  last users of a few private subtype constants that have no generic
  equivalent.

  Patch 7 converts the frame subtype setter and removes the private
  WIFI_* frame type enum.

  Patches 8 and 9 convert the Sequence Control, Duration/ID and QoS
  Control fields.

  Patch 10 replaces the driver's destination and source address
  helpers with ieee80211_get_DA() and ieee80211_get_SA().

None of this should change behaviour. In the few places where a
generic helper checks more than the code it replaces, or where the old
macro kept bits that a plain assignment would overwrite, the commit
message explains why the result is the same.

Compile tested with W=1 after each patch, and checked with checkpatch
and smatch. I don't have a device with this chip, so it has not been
tested on hardware.
