2016-07-18wlcore: Add support for get_expected_throughput opcodeMaxim Altshul
Adding this opcode, allows the TI wireless driver, to report throughput directly from FW to mac80211. This is used mainly for mesh metric calculation. Signed-off-by: Maxim Altshul <maxim.altshul@ti.com> [kvalo@codeaurora.org: fix indentation] Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-07-18dm raid: allow resize during recoveryHeinz Mauelshagen
Resizing a RAID set during recovery can be allowed, because the MD resynchronization thread will either stop any ongoing recovery in case of shrinking below the current recovery position or carry on recovery to the new size if the set is growing.

2016-07-18dm raid: clarify and fix recoveryHeinz Mauelshagen
Add function rs_setup_recovery() to allow for defined setup of RAID set recovery in the constructor. Will be called with dev_sectors={0, rdev->sectors, MaxSectors} to recover a new or enforced sync, grown or not to be synhronized RAID set respectively. Prevents recovery on raid0, which doesn't support it. Enforces recovery on raid6 to ensure properly defined Syndromes mandatory for that MD personality are being created.

Added multirole combination of mesh and ap under the same limits of dual ap mode. 4. Add support for 'sta_rc_update' opcode for mesh IF. The 'sta_rc_update' opcode is being used in mesh_plink.c. Add support in wlcore to handle this opcode correctly for mesh (as opposed to current implementation that handles STA only). 5.

2016-07-18mwifiex: Reduce endian conversion for REG Host CommandsPrasun Maiti
For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS, HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are saved to driver. So, "leX_to_cpu" conversion is required too many times afterwards in driver. This patch reduces the endian: conversion without saving "cpu_to_leX" converted values in driver. This will convert endianness in prepare command and command response path.

2016-07-18eeprom: at24: tweak the loop_until_timeout() macroBartosz Golaszewski
loop_until_timeout() replaced a do {} while loop in the at24 driver with a for loop which, under certain circumstances (such as heavy load or low value of the write_timeout argument), can lead to the code in the loop never being executed.
