category: feature

CVE: NA

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

Add config item CONFIG_TCP_COMP for tcp payload compression.

This allows payload compression handling of the TCP protocol
to be done in-kernel.

This patch only adds the CONFIG_TCP_COMP config, tcp compression
capability is implemented later.
