Using Ethtool flashdev command, entire NVM package (*.pkg) files
may now be staged into the "update" area of the NVM and subsequently
verified and installed by the firmware using the newly introduced
command: NVM_INSTALL_UPDATE.
We also introduce use of the new firmware command FW_SET_TIME so that the
NVM-resident package installation log contains valid time-stamps.

The hardware is unable to drop rx packets not matching the RX filters. To
workaround it, we create a special VNIC and configure the hardware to
direct all packets not matching the filters to it. We then setup the
driver to drop packets received on this VNIC.
This patch creates the infrastructure for this VNIC, reserves a
completion ring, and rx rings. Only shared completion ring mode is
supported. The next 2 patches add a NAPI to handle packets from this
VNIC and the setup of the VNIC.

To prevent that, we call function reset on the 1st PF open before any VF

a bit has been set and we'll skip the function reset. VF driver will
always do function reset on every open. If there is an AER event, we will
