    qat: Add Intel® 4xxx Series platform support · a977168c
    Michal Gulbicki authored
    Overview:
    Intel(R) QuickAssist Technology (Intel(R) QAT) provides hardware
    acceleration for offloading security, authentication and compression
    services from the CPU, thus significantly increasing the performance and
    efficiency of standard platform solutions.
    
    This commit introduces:
    - Intel® 4xxx Series platform support.
    - QuickAssist kernel API implementation update for Generation 4 device.
      Enabled services: symmetric cryptography and data compression.
    - Increased default number of crypto instances in static configuration
      for performance purposes.
    
    OCF backend changes:
    - changed GCM/CCM MAC validation policy to generate MAC by HW
      and validate by SW due to the QAT HW limitations.
