Add a new QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_TX_LATENCY to
configure, retrieve, and report per-link transmit latency statistics.
When used as a command, userspace configures transmit latency monitoring
and get the corresponding statistics of the last period. When used as a
command response, driver replies the get action from userspace with the
statistics of the last period. When used as an event, driver reports the
statistics periodically.
