[PATCH] virt_wifi: Return micros for BSS TSF values

[PATCH] virt_wifi: Return micros for BSS TSF values

[A. Cody Schuffelen]

cfg80211_inform_bss expects to receive a TSF value, but is given the
time since boot in nanoseconds. TSF values are expected to be at
microsecond scale rather than nanosecond scale.
