[PATCH] softmac: avoid assert in ieee80211softmac_wx_get_rate
Unconfigured bcm43xx device can hit an assert() during wx_get_rate queries. This is because bcm43xx calls ieee80211softmac_start late (i.e. during open instead of probe). bcm43xx_net_open -> bcm43xx_init_board -> bcm43xx_select_wireless_core -> ieee80211softmac_start Fix is to check that device is running before completing ieee80211softmac_wx_get_rate.
