Here a series with my idea on how to solve the fact that drivers may not
support or handle all parameters contained in NL80211_CMD_SET_BSS message
as sent by user-space. The driver can announce in the wiphy info which
parameters it supports and user-space can indicate that the kernel may
enforce strict checking for the NL80211_CMD_SET_BSS.

Arend van Spriel (3):
  wifi: nl80211: allow drivers to support subset of NL80211_CMD_SET_BSS
  wifi: drivers; indicate support for attributes in NL80211_CMD_SET_BSS
  wifi: nl80211: strict checking attributes for NL80211_CMD_SET_BSS

Wright Feng (1):
  brcmfmac: support AP isolation to restrict reachability between
    stations

again yuck that this attribute id is a nest in one usage but a flag in another
usage :(
