Update mailbox writes to work with VF devices.

Authored by jhb on Aug 12 2016, 6:32 PM.



Update mailbox writes to work with VF devices.

  • Use alternate register locations for the data and control registers for VFs.
  • Do a dummy read to force the writes to the mailbox data registers to post before the write to the control register on VFs.
  • Do not check the PCI-e firmware register for errors on VFs.
Test Plan
  • tested as part of the VF branch, also tested standalone on PF for basic testing (ping, netperf)
