hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4PNEK


CVE: NA

-------------------------------------------------

When establishing a tcp connection or closing it, the
tcp compression needs to be initialized or cleaned
up at the same time.

Add dummy init and cleanup hook for tcp compression.
It will be implemented later.
