Subject: configure, ipvs plugin: Check for ip_vs.h.
X-Git-Tag: collectd-4.2.0~36
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=fb3a07dc9289ecc2b2752a6b4fa50a32bda89e68;p=collectd.git

configure, ipvs plugin: Check for ip_vs.h.

Disable the ipvs module, if neither net/ip_vs.h nor ip_vs.h could be
found. Added HAVE_*_H checks for each included system header in ipvs.c.
