From 31937c423ed3a13613b3aa7459e7405dd428f2d8 Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Wed, 7 Sep 2011 20:10:02 +0200 Subject: rt2x00: Minor optimizazion in txdone path We can save an indirect function call + some instructions for fetching the actual function pointer by passing the driver specific txwi pointer directly from rt2800pci/rt2800usb to rt2800lib instead of using the rt2800_drv_get_txwi callback.

To achieve this search for an unused WCID in the HW WCID table and assign it to the according STA. When configuring a pairwise key for this STA we don't need to write the MAC address and BSSIDX anymore but just update the crypto related fields in the WCID_ATTR table. This has two advantages: 1) Setting a new key for an already available STA (PTK rekeying) is slightly less expensive and should improve performance in situations where a lot of rekeying happens (e.g. a huge number of stations and/or a small rekeying interval) 2) The TXWI now gets a WCID assigned for unencrypted frames which will be reflected in the corresponding tx status report. This should make tx status reports in unencrypted AP mode more reliable as we can distinguish between multiple key-less STAs.
