Type: fix if the packet is about to be fragmented, then don't call any of the actions that expect the rewrite to have been written. 1) don't double count packets thru the adjacency (original & fragments) 2) don't double decrement the TTL for fragments 3) return to ip4-midchain post ip-frag if that's where we started. 4) only run midchain/mcast fixups if not fragmenting (if no errors) Change-Id: Ib2866787a42713ee5871b87b597d8f74b901044b Signed-off-by: Neale Ranns <nranns@cisco.com>

2019-10-29ip: refactor ip4_mtrie to atomically unset leavesjaszha031-4/+6
ip4_mtrie set leaves atomically in set_leaf () and set_root_leaf () but deleted leaves using regular stores in unset_leaf () and unset_root_leaf (). Changed leaf deletion to update mtrie using atomic store-release. Slight performance improvement was observed in benchmarking on Qualcomm and Xeon machines. Benchmarking involved running 'ip route add' and 'ip route del' on vpp instances. Below are the routes/second for adding and deleting 100k routes before and after the store-release changes: Xeon Add Routes Before: 1.140e6, 1.139e6, 1.148e6, 1.158e6, 1.155e6 Xeon Add Routes After: 1.167e6, 1.170e6, 1.174e6, 1.173e6, 1.169e6 Xeon Del Routes Before: 7.287e7, 8.089e7, 6.048e7, 7.171e7, 7.821e7 Xeon Del Routes After: 8.729e7, 7.353e7, 7.856e7, 8.209e7, 7.787e7 Qualcomm Add Routes Before: 3.709e5, 3.954e5, 3.739e5, 3.759e5, 3.671e5 Qualcomm Add Routes After: 3.879e5, 3.967e5, 3.936e5, 3.764e5, 3.817e5 Qualcomm Del Routes Before: 1.286e7, 1.379e7, 1.353e7, 1.230e7, 1.331e7 Qualcomm Del Routes After: 1.411e7, 1.355e7, 1.373e7, 1.394e7, 1.314e7 Type: refactor Change-Id: If3acd25a2fb87addd0eb13d82d3c8f46579e8060 Signed-off-by: Jason Zhang <jason.zhang2@arm.com> Reviewed-by: Lijian Zhang <Lijian.Zhang@arm.com> Reviewed-by: Ruifeng Wang <ruifeng.wang@arm.com>
