Subject: [PATCH nft] mnl: don't set NLM_F_ACK flag in mnl_nft_rule_batch_[add|del]
Date: Sat,  7 Dec 2013 20:24:22 +0100	[thread overview]
Message-ID: <1386444262-4556-1-git-send-email-pablo@netfilter.org> (raw)

If the NLM_F_ACK flag is unset, the kernel still explicitly reports
errors. Thus, we can save the handling of many explicit (useless) ack
messages that indicate success.
