Not really important now, but maybe we should find a more generic name
for the wl1271_cmd_role_stop_sta() function then.  Or add a nice comment
there saying that it is also used for bss.

This looks wrong.  I didn't see it before, but it was already introduced
in patch 08.  The WL1271_BAND_* definitions are an enumeration defined
like this:

enum wl1271_band {
WL1271_BAND_2_4GHZ = 0,  /* 2.4 Ghz band */
WL1271_BAND_5GHZ = 1,    /* 5 Ghz band */
WL1271_BAND_JAPAN_4_9_GHZ = 2,
WL1271_BAND_DEFAULT = WL1271_BAND_2_4GHZ,
WL1271_BAND_INVALID = 0x7E,
WL1271_BAND_MAX_RADIO = 0x7F,
};

Why are we always ORing the value into cmd->band then? If these commands
can only work in single bands (which is probably the case), then we
should use "cmd->band = WL1271_BAND_5GHZ" instead.  If the commands can
manage more than a band at once, then cmd->band should be a bitmask and
the enumeration should be defined using BIT(0), BIT(1) and so on.
