With this change, we can notify network stack to disable checksum validation for GRO packets as well as other packets which have checksum validation completed earlier in a driver. GRO packets have the ip_summed field set to CHECKSUM_PARTIAL while checksum offloaded packets have the ip_summed field as CHECKSUM_UNNECESSARY. Kernel copies this ip_summed field to the status field in the tpacket filter. The information from the status field is then passed as part of the TUN header to the TUN interface. Any other packet will have the complete checksum validation done in the network stack. Note that this only applies to packets which are captured in packet sockets and passed onto the TUN interface. MTU serves a dual purpose for CLAT. The segment size of the packet ring is based on the MAXMTU apart from the interface MTU itself. GRO coalesce happens on the receive path which is not affected by the MTU (transmit). In other words, increasing the MAXMTU does not affect if a GRO coalesced packet is delivered to CLAT. It only affects the amount of data being read from the TPacket ring. Introduce a new parameter MAXMRU which handles the increased MRU to account for GRO packets. Increase the ring size to compensate for the larger segments to maintain the same throughput as earlier CRs-Fixed: 1023199 Change-Id: I5f5ff05918f3d3e03bb18fe799ccb5770a85038a |
