 Once the slowest lane delay is identified, before enabling the links, SW needs to set the register ''BUFFER_DEALY'' (0x240) from all parallel Rx links if exists based on the following formula:  Once the slowest lane delay is identified, before enabling the links, SW needs to set the register ''BUFFER_DEALY'' (0x240) from all parallel Rx links if exists based on the following formula: 
  
- <m>Buffer Delay = (F*K - min(latency regs + 32)) / TPLDW + 4</m>+ <m>Buffer Delay = (F*K - min(latency regs+ 32) / TPLDW + 4</m>
