Subject: Support dnspython 2.7.0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=11beae640e4a87042f898e5132348436cbbfc523;p=thirdparty%2Fbind9.git

Support dnspython 2.7.0

CookieOption with new .server/.client attributes (rather than .data) was
added to dnspython. Adjust the code to use the new attributes if
available and fall back to the old code for dnspython<2.7.0
compatibility.

(cherry picked from commit 0d90b1364651d9ee5c3495e305187eee11961a42)
