Comment:
Quoting Sam leffler:
{{{
Ok, I understand what's going on now. I was able to reproduce things.
The issue is really an API incompatibility I introduced when I added the
new keycache support in the hal. Before I added the ability to store
TKIP mic keys "combined" the driver would ask the hal if it was capable
of storing TKIP mic keys "together" or "split" using:
if (ath_hal_tkipsplit(ah))
sc->sc_splitmic = 1;
This always evaluated s.t. the driver thought the mic keys were split
across 2 keycache entries and so did the usual work. However when I
added the ability to store the mic keys in a single keycache entry I
made the above call return "the truth". This meant that on parts where
it was possible to store keys either split or combined it said
"together" so sc_splitmic was NOT set to 1. This broke compatibility
with the old driver/existing code.
}}}
Since r1755 madwifi supports the combined tkip entries, so this issue is
mostly null and void.
It was agreed there was little point in modifying the HAL at this point.
