Subject: [net-next 09/15] i40e: move PF ID init from PF reset to SC init

From: Shannon Nelson <shannon.nelson@...el.com>

Move PF ID initialization code from PF reset routine to earlier driver
initialization function.  There are a few operations which need the
PF ID before the first PF reset is called.
