information retrieved from firmware

Patch #6 Fix incorrect mask used while installing filters involving
fragmented packets

Patch #7 Fixes for NPC field hash extract w.r.t IPV6 hash reduction,
         IPV6 filed hash configuration.

Patch #8 Fix for NPC hardware parser configuration destination
         address hash, IPV6 endianness issues.

Patch #9 Fix for skipping mbox initialization for PFs disabled by firmware.

Patch #10 Fix disabling packet I/O in case of mailbox timeout.

Patch #11 Fix detaching LF resources in case of VF probe fail.
