l2: allocate l2fib only when needed
Currently l2 fib allocates 512MB hash table unconditionally on startup.
This patch postpones table creation up to the point where first
interface is put into l2 mode or mac entry is added.
In addition it reduces default table size to 128MB and increases number
of buckets 4 times. This default setting should be enough to keep 1M mac
entries.
Also, new startup.conf section is added which allows user to change memory
and bucket size. .i.e:
l2fib {
table-size 512M
num-buckets 524288
}
Type: improvement
