hihi,
yet another 15% boost from the previous one... it's almost 100gbps for ipv4,
61gbps for ipv6 and 170gbps for mpls...
(that latter again did not changed)... at this time, it was a table
sctructure refactoring...

hihi,
in the past weeks, some big improvements happened to the p4emu core forwarder:
here is the historic snapshot:
https://twitter.com/rare_freerouter/status/1490693899786072067/photo/1
attached the current one... in case of ipv4, it's 10%+, in case of ipv6, it's
20%+,
mpls did not changed as it was a tire structure (and lookup code)
refactoring...

moreover, the dpdk packetio got a bugfix caused it to stop processing packets
from a given nic, because the fwd2nic path could exhaust all of it's mbufs
if the nic2fwd path was much faster somehow...
