Dear John,
Thanks for your help. I am looking in net/mac80211/ibss.c.
I see the ieee80211_rx_mgmt_beacon function but I don't find anything about
beacon tx, or about tsf update. I am still lost.
static void ieee80211_rx_mgmt_beacon(struct ieee80211_sub_if_data *sdata,
struct ieee80211_mgmt *mgmt,
size_t len,
struct ieee80211_rx_status *rx_status)
{
size_t baselen;
struct ieee802_11_elems elems;
/* Process beacon from the current BSS */
baselen = (u8 *) mgmt->u.beacon.variable - (u8 *) mgmt;
if (baselen > len)
return;
ieee802_11_parse_elems(mgmt->u.beacon.variable, len - baselen,
&elems);
ieee80211_rx_bss_info(sdata, mgmt, len, rx_status, &elems, true);
}
Any tip more, please?
Thank you in advance
John
