From 604763722c655c7e3f31ecf6f7b4dafcd26a7a15 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 9 Apr 2007 11:59:39 -0700 Subject: [NET]: Treat CHECKSUM_PARTIAL as CHECKSUM_UNNECESSARY When a transmitted packet is looped back directly, CHECKSUM_PARTIAL maps to the semantics of CHECKSUM_UNNECESSARY. Therefore we should treat it as such in the stack. Signed-off-by: Herbert Xu Signed-off-by: David S.
