Summary

This change introduces Comet Lake Mobile Platform support in the e1000
driver along with shared code patches described below.

  • Cast return value of e1000_ltr2ns() to higher type to avoid overflow
  • Remove useless statement of assigning act_offset
  • Add initialization of identification LED
  • Fix flow control setup after connected standby After connected standby the driver blocks resets during "AdapterStart" and skips flow control setup. This change adds condition in e1000_setup_link_ich8lan() to always setup flow control and to setup physical interface only when there is no need to block resets.
