65 Neighbour hash table buckets are protected with rwlock tbl->lock.
67 - All the scans/updates to hash buckets MUST be made under this lock.
68 - NOTHING clever should be made under this lock: no callbacks
69 to protocol backends, no attempts to send something to network.
72 - If the entry requires some non-trivial actions, increase
76 - with reference count.
77 - with rwlock neigh->lock
81 neigh->lock mainly serializes ll address data and its validity state.

10 * demand-loading started 01.12.91 - seems it is high on the list of
11 * things wanted, and it should be easy to implement. - Linus
15 * Ok, demand-loading was easy, shared pages a little bit tricker. Shared
16 * pages started 02.12.91, seems to work. - Linus.
22 * Also corrected some "invalidate()"s - I wasn't doing enough of them.
28 * 19.12.91 - works, somewhat. Sometimes I get faults, don't know why.
30 * 20.12.91 - Ok, making the swap-device changeable like the root.
34 * 05.04.94 - Multi-page memory management added for v1.1.
37 * 16.07.99 - Support of BIGMEM added by Gerhard Wichert, Siemens AG
