Subject: [PATCH iwl-next v4 03/12] ice: Introduce VF state ICE_VF_STATE_REPLAYING_VC for migration

From: Lingyu Liu <lingyu.liu@...el.com>

During migration device resume stage, part of device state is loaded by
replaying logged virtual channel message. By default, once virtual
channel message is processed successfully, PF will send message to VF.

In addition, PF will notify VF about link state while handling virtual
channel message GET_VF_RESOURCE and ENABLE_QUEUES. And VF driver will
print link state change info once receiving notification from PF.

However, device resume stage does not need PF to send messages to VF
for the above cases. Stop PF from sending messages to VF while VF is
in replay state.
