2019-05-23ice: Silence semantic parser warningsBruce Allan1-2/+2
Recent versions of sparse warn about casting pointers to/from restricted endian types in the Linux driver. Silence those with the compiler attribute __force macro from the Linux kernel to force casts to/from restricted endian types.

2019-02-25ice: fix numeric overflow warningBruce Allan1-3/+4
When compiling and analyzing the driver on newer kernels, a static analyzer warns about the following "numeric overflow" issues: "The result of expression: 'budget-1' generates 4-byte type while casting to a bigger size of 8-byte". "The result of expression: '*words-words_read' generates 4-byte type while casting to a bigger size of 8-byte". Fix them both.

2019-01-15ice: Implement support for normal get_eeprom[_len] ethtool opsBruce Allan1-0/+81
Add support for get_eeprom and get_eeprom_len ethtool ops Specification states that PF software accesses NVM (shadow-ram) via AQ commands (e.g. NVM Read, NVM Write) in the range 0x000000-0x00FFFF (64KB), so the get_eeprom_len op should return 64KB. If additional regions of the 16MB NVM must be read, another access method must be used. The ethtool kernel code, by default, will ask for multiple page-size hunks of the NVM not to exceed the value returned by ice_get_eeprom_len(). ice_read_sr_buf() deals with arch page sizes different than 4KB.

2018-08-28ice: Update request resource command to latest specificationDan Nowlin1-1/+1
Align Request Resource Ownership AQ command (0x0008) to the latest specification. This includes: - Correcting the resource IDs for the Global Cfg and Change locks. - new enum ICE_CHANGE_LOCK_RES_ID - new enum ICE_GLOBAL_CFG_LOCK_RES_ID - Altering the flow for Global Config Lock to allow only the first PF to download the package.

2018-03-26ice: Start hardware initializationAnirudh Venkataramanan1-0/+236
This patch implements multiple pieces of the initialization flow as follows: 1) A reset is issued to ensure a clean device state, followed by initialization of admin queue interface. 2) Once the admin queue interface is up, clear the PF config and transition the device to non-PXE mode. 3) Get the NVM configuration stored in the device's non-volatile memory (NVM) using ice_init_nvm.
