opeations.
v2: Removed redundant tag "UPSTREAM:" in patch title.
Aniket Nagarnaik (3):
mwifiex: add bss mode TLV to extended scan command
mwifiex: use maximum ssid length as 0xfe for p2p
mwifiex: correct p2p and station interface counters

We are setting BSS mode as ANY so that firmware will provide
all types of scan entries.

0xfe is basically a magic number used to ask firmware match
provided string in a SSID. In this case, firmware will
return scan results containing"DIRECT-" string.
