b890d00e84 staging: rtl8188eu: Add missing include
In commit 0a0796eb16, there is no include to mon.h, a newly created

f62cd2cd95 staging: rtl8188eu: issue_action_BA(): extract ADDBA_req pointer
pmlmeinfo->ADDBA_req is accessed three times in this function, but it
contributes to generating lines above 80 characters that are not easy to
split in a nice way.

Extract a pointer to it to make code slightly more concise and fix some
lines over 80 characters.

3e4e8e025c staging: rtl8188eu: don't cast when calling rtw_set_fixed_ie()
The 'pbuf' and 'source' arguments to rtw_set_fixed_ie() are (void *), the
explicit typecasts are not needed. They just make code less readable.

Also fix checkpatch issues in the lines touched:
  ERROR: space prohibited before that ',' (ctx:WxW)
  WARNING: line over 80 characters
  CHECK: Unnecessary parentheses around <var>

Note: some of the modified lines are still over 80 characters because they
are not fixable by just adding newlines. They will be fixed in a later
patch.

3441d08ca2 staging: rtl8188eu: rtw_set_fixed_ie(): accept void* parameters
rtw_set_ie() is a memcpy-like function, taking addresses of memory buffers
among its parameters. Similarly to memcpy, change the parameters to be
void*. This will allow to get rid of typecasts whenever it is called.

0a0796eb16 staging: rtl8188eu: Introduce monitor interface for IEEE 802.11 frames
This adds support for monitoring IEEE 802.11 Data and Management frames
received or transmitted by a RTL8188EU-based device handled by this
driver.

The monitor interface is not enabled by default and will be registered
only if monitor_enable module parameter is set to 1.  When enabled it
will show up as a monX network device, which can be used by the
userspace programs for monitoring network traffic.

It is intended as an exploratory/debugging tool for rtl8188eu driver.
