* i40e: rework debug messages for NVM updateShannon Nelson2014-12-091-27/+80
| | | | | | | | | | | | | | | | | | | Rework the debug messages in the NVM update state machine so that we can turn them on and off dynamically rather than forcing a recompile/reload. These can now be turned on with something like: ethtool -s eth1 msglvl 0xf000008f and off with: ethtool -s eth1 msglvl 0xf000000f The high 0xf0000000 gets the driver's attention that we want to change the internal debug flags, and the 0x80 bit is the NVM debug.

* i40e/i40evf: Add nvmupdate supportShannon Nelson2014-07-241-0/+511
| | | | | | | | | | | | | | | | | | | | | | | | | | | This implements a state machine intended to support the userland tool for updating the device eeprom. The state machine implements one-shot reads, writes, multi-step write sessions, and checksum requests. If we're in the middle of a multi-step write session, no one should fire off other writes, however, one shot reads are valid. The userland tool is expected to keep track of its session status, arrange the placement and ordering of the writes, and deal with the checksum requirement. This patch also adds nvmupdate support to ethtool callbacks. The get_eeprom() and set_eeprom() services in ethtool are used here to facilitate the userland NVMUpdate tool. The 'magic' value in the get and set commands is used to pass additional control information for managing the read and write steps. The read operation works both as normally expected in the standard ethtool method, as well as with the extra NVM controls. The write operation works only for the expanded NVM functions - the normal ethtool method is not allowed because of the NVM semaphore management needed for multipart writes, as well as the checksum requirement.

* i40e: do not take NVM ownership for SR readKamil Krawczyk2014-06-261-8/+1
| | | | | | | | | | We do not need to acquire NVM for Shadow RAM XSUM calculation, as we only read from SR through SRCTL register for which having the ownership is not required.

* i40e: clean up comment styleShannon Nelson2014-03-061-59/+58
| | | | | | | | | | | | | | | | Lots of trivial changes to remove double spaces in function headers, unnecessary periods in short comments, and adjust the English usage here and there. No actual code was harmed in the making of this patch.

* i40e: rework shadow ram read functionsShannon Nelson2014-01-071-51/+16
| | | | | | | | | | | | | | Rework Shadow RAM read word/buffer functions to not use AQ Request Resource commands. Requesting resource is not needed for SR read operations which are done through SRCTL register. Access to SR through register is controlled through DONE bit within SRCTL. With this change we do not block whole NVM resource for SR read operations.
