    mac80211: improve HT channel handling · 0aaffa9b
    Johannes Berg authored
    Currently, when one interface switches HT mode,
    all others will follow along. This is clearly
    undesirable, since the new one might switch to
    no-HT while another one is operating in HT.
    Address this issue by keeping track of the HT
    mode per interface, and allowing only changes
    that are compatible, i.e. switching into HT40+
    is not possible when another interface is in
    HT40-, in that case the second one needs to
    fall back to HT20.
    Also, to allow drivers to know what's going on,
    store the per-interface HT mode (channel type)
    in the virtual interface's bss_conf.
