From 5027309b5581e9c251a46f0ecbf88996d5e0f1e0 Mon Sep 17 00:00:00 2001 From: Daniel C Halperin Date: Fri, 28 Aug 2009 09:44:45 -0700 Subject: iwlwifi: remove 60 Mbps from sband bitrates table ieee80211_supported_band is supposed to only contain legacy rates in the bitrates table (HT rates go in the ieee80211_sta_ht_cap substruct). Make iwlwifi driver obey this restriction by removing the 60 Mbps rate. Also, clean up a few pieces of other code that formerly relied on 60 Mbps being in sband->bitrates.

First, note that HT rates in the mac80211 rate table do not provide valid indices when ieee80211_get_tx_rate is called; the check to see if we could to abort a transmission early in iwl_tx_skb() would thus occasionally read invalid memory and occasionally stall transmission (if the erroneous byte was 0xff). We remove that code; the check wasn't valid anyway. Second, iwl_tx_cmd_build_rate() also called ieee80211_get_tx_rate to be used for sending management packets, which do not use the uCode station table. This patch refactors that function and adds comments to enhance legibility, replaces the call to ieee80211_get_tx_rate() with a direct lookup, and adds error handling in case the table entry is invalid.

However, iwl_hwrate_to_plcp_idx takes the MCS number and reduces it down to the range 0-8 (6 to 60 Mbps), removing the bits that signify multiply streams, HT40 Duplicate mode, or unequal modulation. This version is used for various internal purposes through the driver. Add the function iwl_hwrate_get_mac80211_idx, an alternate version which takes the rate and the band and returns the mac80211 index (MCS, for HT packets, and PLCP rate, for legacy packets).

So let's convert to use a succession of sleep levels when requesting to go to deeper sleeps (which can only happen with large DTIM intervals), using the succession values from power level three, which have the benefit of also having been tested extensively already. As a result, the automatic sleep level adjustment will now be mostly equivalent to power level three, except for the RX/TX timeouts and possibly using smaller sleep vectors to account for networking latency.

Subject: rt2x00: Fix TX status reporting Not all values of the TX status enumeration were covered during updating of the TX statistics. This could lead to wrong bitrate tuning but also wrong behavior in tools like hostapd. Signed-off-by: Ivo van Doorn Signed-off-by: John W.

The entire function was being abused because it had multiple functions and the header length argument was somtimes used to align the header instead of the payload. Additionally there was a bug when inserting L2 padding that only the payload was aligned but not the header. This happens when the header wasn't aligned properly by mac80211, but rt2x00lib only moves the payload. A secondary problem was that when removing L2 padding during TXdone or RX the skb wasn't resized to the proper size. Split the function into seperate functions each handling its task as it should.
