sta is added to FW and in state IEEE80211_STA_NONE  sta->lsta->ni is
0xfffffe00ab574000

IEEE80211_STA_NONE can be from scan-to-auth, assoc-down, run-init.
Given the fc type/subtype this should be an AUTH frame to it should be
scan_to_auth.

However:
vap->iv_bss 0xfffffe00ab79f000 != lvif_bss->ni 0xfffffe00ab574000 but synched
is 1.


Can you apply the following change to give us an idea of how the updates to
iv_bss go (untested):

--- sys/compat/linuxkpi/common/src/linux_80211.c
+++ sys/compat/linuxkpi/common/src/linux_80211.c
@@ -2531,6 +2531,11 @@ lkpi_iv_update_bss(struct ieee80211vap *vap, struct
ieee80211_node *ni)
        lvif = VAP_TO_LVIF(vap);

        LKPI_80211_LVIF_LOCK(lvif);
+       ic_printf(vap->iv_ic, "%s:%d: lvif %p vap %p iv_bss %p lvif_bss %p "
+          "lvif_bss->ni %p synched %d, ni %p\n", __func__, __LINE__,
+          lvif, vap, vap->iv_bss, lvif->lvif_bss,
+          (lvif->lvif_bss != NULL) ? lvif->lvif_bss->ni : NULL,
+          lvif->lvif_bss_synched, ni);
        lvif->lvif_bss_synched = false;
        LKPI_80211_LVIF_UNLOCK(lvif);


Almost also want to dump vap->iv_state here and in lkpi_sta_dump(), if not the
entire history in the latter (taken from ieee80211_ddb.c):

        int i;
        printf("iv_nstate %#x %s iv_nstate_b %d iv_nstate_n %d\n",
            vap->iv_nstate, ieee80211_state_name[vap->iv_nstate], /* historic
*/
            vap->iv_nstate_b, vap->iv_nstate_n);
        for (i = 0; i < NET80211_IV_NSTATE_NUM; i++) {
                printf("\t [%d] iv_nstates %#x %s _task %p _args %d\n", i,
                    vap->iv_nstates[i],
ieee80211_state_name[vap->iv_nstates[i]],
                    &vap->iv_nstate_task[i], vap->iv_nstate_args[i]);
        }
