Subject: Why doesn't RAW use daddr_cache ?
Date: Tue, 15 Jul 2008 10:58:59 +0900	[thread overview]
Message-ID: <487C0463.8070705@miraclelinux.com> (raw)

Hi all,

I have a question about "daddr_cache" in IPv6.

UDP socket uses daddr_cache via p6_sk_dst_lookup()/ip6_dst_store().
But, RAW socket has stopped using it.

I'm afraid of performance degrade in RAW.
Could you please tell me why "daddr_cache" is
deleted in RAW?

Note:
  It's deleted by the following patch.
  commit 6d3e85ecf22a5e3610df47b9c3fb2fc32cfd35bf
  commit 497c615abad7ee81994dd592194535aea2aad617

Regards,
Naohiro Ooiwa
