dpctl: dpif: Allow viewing and configuring dp cache sizes.
This patch adds a general way of viewing/configuring datapath
cache sizes. With an implementation for the netlink interface.
The ovs-dpctl/ovs-appctl show commands will display the
current cache sizes configured:
$ ovs-dpctl show
system@ovs-system:
lookups: hit:25 missed:63 lost:0
flows: 0
masks: hit:282 total:0 hit/pkt:3.20
cache: hit:4 hit-rate:4.54%
caches:
masks-cache: size:256
port 0: ovs-system (internal)
port 1: br-int (internal)
port 2: genev_sys_6081 (geneve: packet_type=ptap)
port 3: br-ex (internal)
port 4: eth2
port 5: sw0p1 (internal)
port 6: sw0p3 (internal)
A specific cache can be configured as follows:
$ ovs-appctl dpctl/cache-set-size DP CACHE SIZE
$ ovs-dpctl cache-set-size DP CACHE SIZE
For example to disable the cache do:
$ ovs-dpctl cache-set-size system@ovs-system masks-cache 0
Setting cache size successful, new size 0.
