We do send that command on all other type-changes though, and it probably makes sense to send the command since after all we just changed our BSS_MODE. Looking at prior changes to this part of the code, it seems that this is simply a leftover from old refactorings. Since sending the SET_BSS_MODE command is the only difference between mwifiex_change_vif_to_sta_adhoc() and the current code, we can now use mwifiex_change_vif_to_sta_adhoc() for both switching to ADHOC and STATION interface type. This does not fix any particular bug and just "looked right", so there's a small chance it might be a regression.
