gtpu: Track the dst FIB entry instead of RR sourcing that
RR sourcing the destination FIB entry limits the number of tunnels to 255 for a particular destination. This change removes this limit. Type: fix The patch is based on 1f50bf8fc57ebf78f9056185a342493be460a847 that introduced the FIB entry tracking but did not update the gtpu plugin. Signed-off-by: Miklos Tirpak <miklos.tirpak@gmail.com> Change-Id: I8a4a87382a6eb5120e2bb65b9bc3c446bbfdbd3b (cherry picked from commit 75c72369186f6341a13374d2dd6e60ce3c7a88a6)
