Subject: Conditionalize use of IF_MAXUNIT in virnetdevtap.c
X-Git-Tag: CVE-2013-2218~10
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=002c8af9f0c2e30421c79680588b28802b012d0a;p=thirdparty%2Flibvirt.git

Conditionalize use of IF_MAXUNIT in virnetdevtap.c

The IF_MAXUNIT macro is not present on all BSDs, so
make its use conditional, to avoid breaking OS-X.
