ignore_bss_tm_candidates: When a BSS requests a station roam it can optionally include a list of BSS's that can be roamed to. IWD uses this list and only scans on those frequencies. In some cases though the AP's list contains very poor options and it would be better for IWD to request a full neighbor report. replay_counter_mismatch: On some Aruba APs there is a mismatch in the replay counters between what is seen in scans versus authentications/associations. This difference is not allowed in the spec, therefore IWD will not connect. This quirk is intended to relax that check.
