[v3,0/5] initial S1G defines

Message

This patchset finishes the work to make channels work on a KHz offset,
and includes the initial definitions for S1G (802.11ah).

These patches on top of wt-2020-04-29 with hostap c54a5e96b505 gives the
following hwsim test results:

Failed even on retry:
proxyarp_open_ebtables wpas_config_file fst_dynamic_iface_attach
TOTAL=3531 PASS=3265 FAIL=12 SKIP=251

Which is what we currently expect of HEAD.

Changes from v3 are rebasing on latest wireless-testing and making the
SCAN_FREQ_KHZ more robust so userspace can omit the MHZ-only scan
frequencies in the request, and kernel can do the same in the results.

Also some breakage introduced by patch #1 has been addressed by leaving
the existing cfg80211 API intact.

Thomas Pedersen (5):
  cfg80211: add KHz variants of frame RX API
  nl80211: add KHz frequency offset for most wifi commands
  nl80211: support scan frequencies in KHz
  ieee80211: S1G defines
  nl80211: S1G band and channel definitions
