2018-10-17net: qla3xxx: Remove overflowing shift statementNathan Chancellor
Clang currently warns: drivers/net/ethernet/qlogic/qla3xxx.c:384:24: warning: signed shift result (0xF00000000) requires 37 bits to represent, but 'int' only has 32 bits [-Wshift-overflow] ((ISP_NVRAM_MASK << 16) | qdev->eeprom_cmd_data)); ~~~~~~~~~~~~~~ ^ ~~ 1 warning generated. The warning is certainly accurate since ISP_NVRAM_MASK is defined as (0x000F << 16) which is then shifted by 16, resulting in 64424509440, well above UINT_MAX. Given that this is the only location in this driver where ISP_NVRAM_MASK is shifted again, it seems likely that ISP_NVRAM_MASK was originally defined without a shift and during the move of the shift to the definition, this statement wasn't properly removed (since ISP_NVRAM_MASK is used in the statenent right above this). Only the maintainers can confirm this since this statment has been here since the driver was first added to the kernel.

2018-10-17octeontx2-af: Support for disabling NIX RQ/SQ/CQ contextsGeetha sowjanya
This patch adds support for a RVU PF/VF to disable all RQ/SQ/CQ contexts of a NIX LF via mbox. This will be used by PF/VF drivers upon teardown or while freeing up HW resources. A HW context which is not INIT'ed cannot be modified and a RVU PF/VF driver may or may not INIT all the RQ/SQ/CQ contexts. So a bitmap is introduced to keep track of enabled NIX RQ/SQ/CQ contexts, so that only enabled hw contexts are disabled upon LF teardown.

2018-10-17octeontx2-af: Forward CGX link notifications to PFsLinu Cherian
Upon receiving notification from firmware the CGX event handler in the AF driver gets the current link info such as status, speed, duplex etc from CGX driver and sends it across to PFs who have registered to receive such notifications. To support above - Mbox messaging support for sending msgs from AF to PF has been added. - Added mbox msgs so that PFs can register/unregister for link events. - Link notifications are sent to PF under two scenarioss. 1. When a asynchronous link change notification is received from firmware with notification flag turned on for that PF. 2. Upon notification turn on request, the current link status is send to the PF. Also added a new mailbox msg using which RVU PF/VF can retrieve their mapped CGX LMAC's current link info. Link info includes status, speed, duplex and lmac type.
