rtlwifi: rtl818x: Move drivers into new realtek directory

2015-10-14T10:33:10+00:00

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. Signed-off-by: Larry Finger Signed-off-by: Kalle Valo

rtlwifi: Update power-save routines for 062814 driver

2014-09-26T21:22:28+00:00

Realtek released a new version of the drivers on 06/28/2014. This patch implements the new power-save code. These changes also force corresponding changes in the drivers. Signed-off-by: Larry Finger Signed-off-by: John W. Linville

rtlwifi: Remove casts of pointer to same type

2014-03-27T18:20:05+00:00

Casting a pointer to a pointer of the same type is pointless, so remove these unnecessary casts. Around these changes: o Remove unnecessary parentheses o Use consistent dereference style (change ptr[0] to *ptr) o Argument alignment Done via coccinelle script: (and some typing) $ cat typecast_2.cocci @@ type T; T *foo; @@ - (T *)foo + foo Signed-off-by: Joe Perches Signed-off-by: John W.

rtlwifi: Fix incorrect return from rtl_ps_enable_nic()

2014-02-13T19:58:12+00:00

rtl_ps_enable_nic() is called from loops that will loop until this function returns true or a maximum number of retries is performed. hw_init() returns non-zero on error. In that situation return false to restore the original design intent to retry hw init when it fails. Signed-off-by: Olivier Langlois Cc: Stable Acked-by: Larry Finger Signed-off-by: John W. Linville

rtlwifi: use ether_addr_equal_64bits

2014-01-03T20:36:59+00:00

Ether_addr_equal_64bits is more efficient than ether_addr_equal, and can be used when each argument is an array within a structure that contains at least two bytes of data beyond the array. The structures involved are: ieee80211_hdr defined in include/linux/ieee80211.h and rtl_mac defined in drivers/net/wireless/rtlwifi/wifi.h This was done using Coccinelle (http://coccinelle.lip6.fr/).

drivers/net: Convert uses of compare_ether_addr to ether_addr_equal

2013-09-04T02:28:04+00:00

Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting.

rtlwifi: Fix build errors for unusual cases

2013-07-18T20:22:00+00:00

The present build configuration for the rtlwifi family of drivers will fail under two known conditions: (1) If rtlwifi is selected without selecting any of the dependent drivers, there are errors in the build. (2) If the PCI drivers are built into the kernel and the USB drivers are modules, or vice versa, there are missing globals. The first condition is fixed by never building rtlwifi unless at least one of the device drivers is selected. The second failure is fixed by splitting the PCI and USB codes out of rtlwifi, and creating their own mini drivers. If the drivers that use them are modules, they will also be modules. Although a number of files are touched by this patch, only Makefile and Kconfig have undergone significant changes. The only modifications to the other files were to export entry points needed by the new rtl_pci and rtl_usb units, or to rename two variables that had names that were likely to cause namespace collisions.

rtlwifi: Initialize power-setting callback for USB devices

2013-07-17T18:34:48+00:00

Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue" has two bugs for USB drivers. Firstly, the work queue in question was not initialized. Secondly, the callback routine used by this queue is contained within the file used for PCI devices. As a result, it is not available for architectures without PCI hardware.
