From f9d106a6d53b57b78eae5544f9582c643343a764 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 23 Apr 2007 22:36:13 -0700 Subject: [PATCH] [NET]: Warn about GSO/checksum abuse Now that Patrick has added the code to deal with GSO in netfilter, we no longer need the crutch that computes partial checksums just before transmission. This patch turns this into a warning again. If this goes OK, we can then turn it into a BUG_ON and remove the gso_send_check cruft. Signed-off-by: Herbert Xu Signed-off-by: David S.
