Description

Linux commits:
v5.7-rc6-2504-gddd061b8daed
tcp: add tcp_sock_set_quickack

v5.7-rc6-2508-gd41ecaac903c
tcp: add tcp_sock_set_keepintvl

v5.7-rc6-2509-g480aeb9639d6
tcp: add tcp_sock_set_keepcnt

Introduced a series of helper functions that may be
back ported individually.
In this case it breaks building SUSE 15 SP3

Add the some configure treatment for these as was done previously for
tcp_sock_set_nodelay() and tcp_sock_set_keepidle()
