Subject: [PATCH v2] virt_wifi: Return micros for BSS TSF values
Date: Thu, 18 Mar 2021 13:04:19 -0700 [thread overview]
Message-ID: <20210318200419.1421034-1-schuffelen@google.com> (raw)
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.
