* rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger2015-10-141-302/+0
| | | | | | | | | | | | Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.

* rtlwifi: Add encryption argument in rtl_is_special_data for checking DHCP ↵Taehee Yoo2015-04-071-2/+3
| | | | | | | | | | | | | | | | | packet. rtl8192cu can't connect to AP after physical reconnect. according to dmesg, that problem's cause was DHCP timeout. rtl_is_special_data function checks packet type for adjusting rate. when that function is called from _rtl_rc_get_highest_rix, it can not calculate offset correctly. so i add argument is_encn in rtl_is_special_data. is_enc variable mean that iv header is added in skb parameter. i test only rtl8192cu chipset. because i doesn't have other rtlwifi chipsets.

* mac80211: remove module handling from rate control opsJohannes Berg2014-02-041-1/+0
| | | | | | | | | | | | There's not a single rate control algorithm actually in a separate module where the module refcount would be required. Similarly, there's no specific rate control module. Therefore, all the module handling code in rate control is really just dead code, so remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40Johannes Berg2013-02-151-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For VHT, many more bandwidth changes are possible. As a first step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag in the HT capabilities and instead introduce a bandwidth field indicating the currently usable bandwidth to transmit to the station. Of course, make all drivers use it. To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get the station as an argument, rather than the new capabilities, so it can set up the new bandwidth field. If the station is a VHT station and VHT bandwidth is in use, also set the bandwidth accordingly. Doing this allows us to get rid of the supports_40mhz flag as the HT capabilities now reflect the true capability instead of the current setting. While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not ignore HT cap overrides when MCS TX isn't supported (not that it really happens...)

* | rtlwifi: Initialize rate_init member of struct rate_control_opsCatalin Iacob2013-02-121-0/+7
|/ | | | | | | | | | | | | | | | This partially reverts commit 44ba973699b831414c3f8eef68ee5a7fe1208a05. rate_control_rate_init assumes the rate_init member of struct rate_control_ops is not NULL therefore not initializing it leads to an oops as soon the driver succesfully associates to an AP. The removal of rate_update from 44ba973699b831414c3f8eef68ee5a7fe1208a05 is ok because rate_update is checked for NULL before being called.

| | | | | | | | | | | | | | the new driver This patch completes the addition of the new driver for the Realtek RTL8723AE devices by adding the make file and by modifying Kconfig and Makefile of rtlwifi. Some variable names were shortened to ease the problem of limiting all lines to 80 characters, thus changes were made to wifi.h and rtl8192{ce,cu,sw}/hw.c.

* mac80211: remove channel type argument from rate_updateJohannes Berg2012-04-101-2/+1
| | | | | | | | | | | | | | | The channel type argument to the rate_update() callback isn't really the correct way to give the rate control algorithm about the desired RX bandwidth of the peer. Remove this argument, and instead update the STA capabilities with 20/40 appropriately. The SMPS update done by this callback works in the same way, so this makes the callback cleaner.
