2019-03-12ICMP46 error: Clone first buffer instead of "truncating" original bufferOle Troan1-22/+17
Previous code was walked buffer chain, effectively trying to "truncate" the chain, reset the length of first buffer and reused that as the ICMP error message. That could have issues in cases there were other users of the buffer chain. Update to clone the first buffer in chain, and use that for the ICMP error message instead.

2018-10-27pg: icmp4 & tcp4 ip length issueKingwel Xie1-1/+7
length in ip4 header could be 0, when the length edit is fixed this happens if length is not specified or size is specified as, f.g., 100-100 As a result, tcp and icmp would get a negative value for checksum calculation Change-Id: I55fa1f5e95717ea4149cb3b8c9b73caf88ae7f98 Signed-off-by: Kingwel Xie <kingwel.xie@ericsson.com>
