Amitkumar Karwar 21c3ba3464 mwifiex: use IEEE80211_HT_PARAM_CHA_SEC_* macros
Replace driver specific macros with the corresponding
IEEE80211_HT_PARAM_CHA_SEC_* macros defined in ieee80211.h.
Also, rename 'adapter->chan_offset' to 'adapter->sec_chan_offset'
for consistency.

Amitkumar Karwar 7c6fa2a843 mwifiex: use cfg80211 dynamic scan table and cfg80211_get_bss API
Instead of maintaining static scan table in driver, scan list is sent
to cfg80211 stack (after parsing each scan command response).
In assoc handler (for infra and ibss network) requested BSS information
is retrieved using cfg80211_get_bss() API.

With the changes above some redundant code are removed.

Amitkumar Karwar 7cc5eb629c mwifiex: remove unnecessary struct mwifiex_opt_sleep_confirm_buffer
The structure definition is
struct mwifiex_opt_sleep_confirm_buffer {
       u8 hdr[4];
       struct mwifiex_opt_sleep_confirm ps_cfm_sleep;
} __packed;

For sleep_confirm command we already reserve 4 bytes (using skb_reserve())
for an interface header. It will be filled later by interface specific code.
We don't need "hdr[4]" element in above structure. So we can use
"struct mwifiex_opt_sleep_confirm" directly instead of
"struct mwifiex_opt_sleep_confirm_buffer".

Marc Yang 6d2bd916af mwifiex: use IEEE80211_HT_CAP_ macros for 11n cap_info
The hw_dot_11n_dev_cap reported by firmware hw_spec
has different format than the 11n capabilities.
Hence a lot of SET_ and RESET_ bit operation macros
were used to convert the dev_cap format to 11n
capability format. However the locally defined 11n
ht_cap macros are not necessary as we can use
IEEE80211_HT_CAP_ macros directly.

The 32-bit dev_cap bitmap is added as comment to
explain the mapping between firmware and 11n spec.

Some unused macros and unnecessary adapter variables
are also removed.
