Skyhawk P1 firmware can be downloaded to Skyhawk P2 cards. Skyhawk-P1 FW
UFI is not compatible to flash on Skyhawk-P2 ASIC. These patches will
avoid flashing P1 firmware on P2 card.

We have a number of OEMs rolling on Skyhawk P2 ASIC support for their
adapters over the next 6-12 months. We need to ensure this fix gets in
in order to prevent Skyhawk B0 ASIC images being inadvertently
downloaded to the P2 ASICs.

If a B0 image is downloaded to a P2 ASIC, it will boot and run but the
functionality will not operate correctly.

All of the traditional Tier 1 Server vendors are rolling out the P2 ASIC
in the coming year and are in qual now. Please consider including this
change as an exception into 14.04 Stable release update and 14.04.3 once
that git tree is available.
