Subject: Protocol checksums have been recalculated on reinjection for a while
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=b701d7088b83263019276606d36a2220e20c5a06;p=openbsd

Protocol checksums have been recalculated on reinjection for a while
now, so there is no need to calculate them before sending them to
userspace.
