WebbIn this paper we show a real-world example where we created a common network function, RSS, using both traditional RTL/Verilog tools and then using high-level synthesis (HLS) on the same hardware. What we found was surprising: the HLS approach actually used fewer FPGA gates and memory. There is a reason. Read on for details.

Capable hardware can pass the hash in the receive descriptor for the packet; this would usually be the same hash used for RSS (e.g. computed Toeplitz hash). The hash is saved in skb->hash and can be used elsewhere in the stack as a hash of the packet’s flow. city of san bernardino graffiti removal
