cxgb4: add support for offloading u32 filters
Add support for offloading u32 filter onto hardware. Links are stored
in a jump table to perform necessary jumps to match TCP/UDP header.
When inserting rules in the linked bucket, the TCP/UDP match fields
in the corresponding entry of the jump table are appended to the filter
rule before insertion. If a link is deleted, then all corresponding
filters associated with the link are also deleted. Also enable
hardware tc offload as a supported feature.
