bnx2x: Allow more than 64 L2 CIDs
With increased number of RSS queues, each multiplied by the number of traffic-
classes, we may have up to 64*3=192 CIDs. The current driver scheme with regard
to context allocation supports only 64 CIDs. The new scheme enables scatter-
gatehr list of pages for the context.
