Hi Pablo, Deprecated nfq_set_queue_flags documents flag NFQA_CFG_F_FAIL_OPEN for kernel to accept packets if the kernel queue gets full. Does this still work with libmnl?I'm thinking we need a new "Library Setup [CURRENT]" section to document available flags (including e.g. NFQA_CFG_F_GSO that examples/nf-queue.c uses). Maybe we need Attribute helper functions as well? (documentation *and* new code). Cheers ... Duncan.
