Subject: [PATCH net-next 9/9] tipc: eliminate configuration for maximum number of name publications
From: Ying Xue <ying.xue@...driver.com>
Gets rid of the need for users to specify the maximum number of
name publications supported by TIPC. TIPC now automatically provides
support for the maximum number of name publications to 65535.
