net: filter: simplify label names from jump-table
This patch simplifies label naming for the BPF jump-table. When we define labels via DL(), we just concatenate/textify the combination of instruction opcode which consists of the class, subclass, word size, target register and so on. Each time we leave BPF_ prefix intact, so that e.g. the preprocessor generates a label BPF_ALU_BPF_ADD_BPF_X for DL(BPF_ALU, BPF_ADD, BPF_X) whereas a label name of ALU_ADD_X is much more easy to grasp. Pure cleanup only. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Acked-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S. Miller <davem@davemloft.net>
