It appears that ieee80211_tx_status also scales poorly
when using large numbers of virtual stations connected
to a single AP, due to for_each_sta_info(local, hdr->addr1, sta, tmp)...
I'm going to try using the vif-hashing to make this faster,
but first a question:
Since it matches on MAC addresses, should it
just return at the bottom of the loop since it has
found a match, and MACs are supposed to be unique?
for_each_sta_info(local, hdr->addr1, sta, tmp) {
/* skip wrong virtual interface */
if (!ether_addr_equal(hdr->addr2, sta->sdata->vif.addr))
continue;
...
If so, that would be a good improvement since the hash can easily
be turned into a linear search even in AP mode (without all of
my virtual-station scenarios)...
Thanks,
Ben
