2016-03-10rtl8xxxu: Fix incorrect test for auto LLT failureJes Sorensen1-4/+1
The logic for testing auto load failure in rtl8xxxu_auto_llt_table() was inverted. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Init the LLT after we start the firmwareJes Sorensen1-9/+9
To match the flow of the vendor driver, move the LLT init to after the firmware is started. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Init page boundaries before starting the firmwareJes Sorensen1-34/+34
This reorganizes the device initialization to init page boundaries before starting the firmware. This matches the flow in the 8192eu vendor driver. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Add rtl8xxxu_auto_llt_table()Jes Sorensen3-1/+36
Newer chips can auto load the LLT table, it is no longer necessary to build it manually in the driver. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Implment rtl8192eu_power_on()Jes Sorensen2-6/+133
This implements the rtl8192eu power on sequence, and splits it off from the rtl8192cu/rtl8723au power on sequence. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Add rtl8192eu_nic.bin to the MODULE_FIRMWARE listJes Sorensen1-0/+1

2016-03-10rtl8xxxu: Use 1024 byte block loads for 8192eu firmwareJes Sorensen1-1/+1
The rtl8192eu can handle 1024 byte block writes, unlike it's predecessors (8192cu/8188cu). Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Identify chip vendors correctlyJes Sorensen3-15/+64
This identifies the chip vendors correctly and also picks the correct firmware for rtl8192eu. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-10rtl8xxxu: Add initial code to parse rtl8192eu efuseJes Sorensen2-6/+124
This is the start of 8192eu support. For now just detect the device and parse the efuse. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-08rtlwifi: Fix size of wireless mode variableLarry Finger3-8/+7
Smatch reports the following warning: CHECK drivers/net/wireless/realtek/rtlwifi/rc.c drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series() warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)' This warning arises because commit acc6907b87a9 ("rtlwifi: Fix warning from ieee80211_get_tx_rates() when using 5G") now checks the wireless mode for WIRELESS_MODE_AC_ONLY (BIT(8)) in _rtl_rc_rate_set_series(). As a result, all quantities used to store the wireless mode must be u16. This patch also reorders struct rtl_sta_info to save a little space. Fixes: d76d65fd2695 ("rtlwifi: fix broken VHT support") Reported-by: Dan Williams <dcbw@redhat.com> Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-07rtlwifi: pass struct rtl_stats by reference as it is more efficientColin Ian King12-16/+16
passing rtl_stats by value is inefficient; the structure is over 300 bytes in size and generally just one field (packet_report_type) is being accessed, so the pass by value is a relatively large overhead. This change just affects just the rx_command_packet calls. Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-03-07rtlwifi: Change long delays to sleepsLarry Finger1-32/+12
Routine rtl_addr_delay() uses delay statements in code that can sleep. To improve system responsiveness, the various delay statements are changed. In addition, routines rtl_rfreg_delay() and rtl_bb_delay() are rewritten to use the code in rtl_addr_delay() for most of their input values.

2016-03-07rtlwifi: rtl8821ae: Silence useless log outputLarry Finger1-1/+1
When driver rtl8821ae is loaded but not connected to any AP, it logs a "firmware not ready to run" message roughly once a minute. To eliminate logging this massage under normal debug conditions, the degug level needed to print this message is increased.

2016-02-25rtlwifi: rtl8821ae: Convert driver to use common 5G channel tableLarry Finger3-40/+7
There are several copies of the 5G channel tables in this driver. These are removed so that the tables in the core will be used. This change also removes a useless message of "Channel 163 in Group not found". The number of possible 5G channels was reduced from 54 to a better value of 49 during the conversion.

2016-02-25rtlwifi: rtl8192ee: Convert driver to use new 5G channel tablesLarry Finger1-12/+0
The driver defines its own set of channel tables for the 5G band. With this change, it will use those of the core. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-02-25rtlwifi: Prepare for reworking 5G channelsLarry Finger2-5/+20
There are 3 drivers in this family that have 5G radios. Each of them defines local copies of the available channels. This patch adds the two arrays to the core driver. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-02-25rtlwifi: Remove unnecessary synchronize_irq() before free_irq()Lars-Peter Clausen1-1/+0
Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way), before any state associated with the IRQ is freed. Patch was generated using the following semantic patch: // <smpl> @@ expression irq; @@ -synchronize_irq(irq); free_irq(irq, ...); // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-02-25rtl8xxxu: Set correct bit to reset MCU IO wrapperJes Sorensen1-2/+2
All chips, except for 8812 require BIT(0) for resetting the MCU IO wrapper. 8723b requires a more complicated reset sequence, so it will need a custom reset function. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

mac80211 documentation says, the ieee80211_ops.start callback "must turn on frame reception (for possibly enabled monitor interfaces.)". If not a single monitor interface does not receive data frames. Similarly we should not change the data reception based on the association state.

2016-02-25rtl8xxxu: Enable monitor mode by handling filtersBruno Randolf1-11/+45
Monitor mode is enabled by handling the filter flags we get from mac80211 in rtl8xxxu_configure_filter() and writing them to the RCR register. By handling the filters, we can also stop setting the BSSID filters in the association event.
