Subject: ldpd: fix broken label allocation
X-Git-Tag: frr-4.0-dev~316^2~1

ldpd: fix broken label allocation

Once ldpd allocated label 48 for a given FEC, all subsequent requests
for a new label would return the same value (48). The problem is that
we were left shifting an uint32_t value up to 64 times, losing important
information.
