nfp: bpf: make array exp_mask static, makes object smaller
Don't populate the array exp_mask on the stack but instead make it static. Makes the object code smaller by 224 bytes. Before: text data bss dec hex filename 77832 2290 0 80122 138fa ethernet/netronome/nfp/bpf/jit.o After: text data bss dec hex filename 77544 2354 0 79898 1381a ethernet/netronome/nfp/bpf/jit.o (gcc version 9.2.1, amd64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>
