From 48bc41a49c4f3aa760dff84e7f71437f5ed520fe Mon Sep 17 00:00:00 2001 From: Stephen Hemminger <shemminger@osdl.org> Date: Tue, 6 Sep 2005 15:51:48 -0700 Subject: [PATCH] [IPV4]: Reassembly trim not clearing CHECKSUM_HW This was found by inspection while looking for checksum problems with the skge driver that sets CHECKSUM_HW. It did not fix the problem, but it looks like it is needed. If IP reassembly is trimming an overlapping fragment, it should reset (or adjust) the hardware checksum flag on the skb.
