which was incorrect, so revert that portion of the commit to have the

The "u16 CcxRmState[2];" array field in struct "rtllib_network" has 4
bytes in total while the operations performed on this array through-out
the code base are only 2 bytes.
The "CcxRmState" field is fed only 2 bytes of data using memcpy():
(In rtllib_rx.c:1972)
memcpy(network->CcxRmState, &info_element->data[4], 2)
With "info_element->data[]" being a u8 array, if 2 bytes are written
into "CcxRmState" (whose one element is u16 size), then the 2 u8
elements from "data[]" gets squashed and written into the first element
("CcxRmState[0]") while the second element ("CcxRmState[1]") is never
fed with any data.
Same in file rtllib_rx.c:2522:
memcpy(dst->CcxRmState, src->CcxRmState, 2);
The above line duplicates "src" data to "dst" but only writes 2 bytes
(and not 4, which is the actual size). Again, only 1st element gets the
value while the 2nd element remains uninitialized.
This later makes operations done with CcxRmState unpredictable in the
following lines as the 1st element is having a squashed number while the
2nd element is having an uninitialized random number.
rtllib_rx.c:1973: if (network->CcxRmState[0] != 0)
rtllib_rx.c:1977: network->MBssidMask = network->CcxRmState[1] & 0x07;
network->MBssidMask is also of type u8 and not u16.
Fix this by changing the type of "CcxRmState" from u16 to u8 so that the
data written into this array and read from it make sense and are not
random values.
NOTE: The wrong initialization of "CcxRmState" can be seen in the
following commit:
commit ecdfa44610 ("Staging: add Realtek 8192 PCI wireless driver")
The above commit created a file `rtl8192e/ieee80211.h` which used to
have the faulty line. The file has been deleted (or possibly renamed)
with the contents copied in to a new file `rtl8192e/rtllib.h` along with
additional code in the commit 94a799425e (tagged in Fixes).

The variable "info_element" is of the following type:
struct rtllib_info_element *info_element
defined in drivers/staging/rtl8192e/rtllib.h:
struct rtllib_info_element {
u8 id;
u8 len;
u8 data[];
} __packed;
The "len" field defines the size of the "data[]" array. The code is
supposed to check if "info_element->len" is greater than 4 and later
equal to 6. If this is satisfied then, the last two bytes (the 4th and
5th element of u8 "data[]" array) are copied into "network->CcxRmState".
Right now the code uses "memcpy()" with the source as "&info_element[4]"
which would copy in wrong and unintended information. The struct
"rtllib_info_element" has a size of 2 bytes for "id" and "len",
therefore indexing will be done in interval of 2 bytes. So,
"info_element[4]" would point to data which is beyond the memory
allocated for this pointer (that is, at x+8, while "info_element" has
been allocated only from x to x+7 (2 + 6 => 8 bytes)).
This patch rectifies this error by using "&info_element->data[4]" which
correctly copies the last two bytes of "data[]".
NOTE: The faulty line of code came from the following commit:
commit ecdfa44610 ("Staging: add Realtek 8192 PCI wireless driver")
The above commit created the file `rtl8192e/ieee80211/ieee80211_rx.c`

possibly renamed) with the contents copied in to a new file
`rtl8192e/rtllib_rx.c` along with additional code in the commit
94a799425e (tagged in Fixes).
