staging: vt6655: mac80211 conversion add main mac80211 functions
Replace existing vt6655_probe with one converted to mac80211 with the following operations vnt_tx_80211 vnt_start vnt_stop vnt_add_interface vnt_remove_interface vnt_config vnt_bss_info_changed vnt_prepare_multicast vnt_configure vnt_set_key vnt_get_tsf vnt_set_tsf vnt_reset_tsf The following variables are also added. basic_rates mc_list_count mac_hw Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
