Daniel Borkmann	4dd3f50af4	tc, bpf: add support for map pre/allocation ... Follow-up to kernel commit 6c9059817432 ("bpf: pre-allocate hash map elements"). Add flags support, so that we can pass in BPF_F_NO_PREALLOC flag for disallowing preallocation. Update examples accordingly and also remove the BPF_* map helper macros from them as they were not very useful. Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>	2016-04-11 21:54:47 +00:00
