[RFC PATCH 0/4] inet: add second hash table

[Alexandru Copot <alex.mihai.c@gmail.com>]

This patchset implements all the operations needed to use a second
(port,address) bind hash table for inet. It uses a similar approach
as the UDP implementation.

The performance improvements for port allocation are very good and
detailed in the last message.

This is based on a series of patches written by Lucian Grijincu at Ixia.
