X-Git-Tag: libnl2_0~144
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5618ea8f5a1cf417fec434788b4b14cc7fcbe246;p=libnl

[LIBNL]: nfnetlink_log: only set hwproto if not zero

The hwproto doesn't have its own attribute and is also present when
not set. Don't set the attribute if its value is zero.
