From: Maor Gottlieb <redacted> Create the following four flow tables for aRFS usage: 1. IPv4 TCP - filtering 4-tuple of IPv4 TCP packets. 2. IPv6 TCP - filtering 4-tuple of IPv6 TCP packets. 3. IPv4 UDP - filtering 4-tuple of IPv4 UDP packets. 4. IPv6 UDP - filtering 4-tuple of IPv6 UDP packets. Each flow table has two flow groups: one for the 4-tuple filtering (full match) and the other contains * rule for miss rule. Full match rule means a hit for aRFS and packet will be forwarded to the dedicated RQ/Core, miss rule packets will be forwarded to default RSS hashing.

this line breaks the build when RFS is on and CONFIG_MLX5_CORE_EN is off.
