xfrm: Increase the garbage collector threshold
With the removal of the routing cache, we lost the option to tweak the garbage collector threshold along with the maximum routing cache size. So git commit 703fb94ec ("xfrm: Fix the gc threshold value for ipv4") moved back to a static threshold. It turned out that the current threshold before we start garbage collecting is much to small for some workloads, so increase it from 1024 to 32768. This means that we start the garbage collector if we have more than 32768 dst entries in the system and refuse new allocations if we are above 65536.
