2018-11-14linux-gen: ishm: read single va size from configMatias Elo
Simplify adjusting single VA memory size by moving the value to ODP config (shm.single_va_size). The default size is dropped to 128MB to save memory.

2018-10-29linux-gen: ipsec: make SA lifetime checking more scalable to multiple threadsJanne Peltonen
Enforcing the packet and byte based SA life times is currently slow if the same SA is being handled by multiple threads since the threads keep checking and updating the same shared byte and packet counters. Make the implementation more scalable by having a thread-local quota of packets and bytes for each SA and by updating the shared byte and packet counters less frequently (i.e. when the quota runs out). This introduces some inexactness to life time warnings and errors. The warnings and errors about soft and hard limits being reached may come a bit earlier than expected based on the packets sent to the wire.
