 <li>Various kernel improvements:
   <ul>
+  <li>pf(4) automatically allows IGMP and ICMP6 MLD packets with
+    router alert option.
+    Special allow-opts rules are no longer needed for multicast
+    discovery.
+  <li>Implement "show all routes" to print routing tables in ddb(4).
+  <li>Count dropped network packets due to low memory in netstat(1).
   <li>...
   </ul>
 
 <li>SMP Improvements
   <ul>
+  <li>Make route timer MP safe and use pool rttmr.
+  <li>Use kernel lock to protect parts of ARP, ND6 and PPPoE that
+    are not MP safe.
+    Lookup of existing ARP entry is MP safe and can run in parallel.
+  <li>Start up to 4 softnet tasks to run IP input and forwarding
+    in parallel on multiple cores.
+  <li>Run IPv4 packet reassembly in parallel.
+  <li>Run IPv6 hop-by-hop options processing in parallel.
+  <li>Add a mutex to rate limiting functions to make them MP safe.
+  <li>Introduce mutex and reference counter for internet protocol 
+    control block.
+  <li>Protect UDP, raw IP, and divert packet input routines
+    with a per socket mutex.
+  <li>Protect recv(2) system call for UDP and raw IP packets with
+    a per socket mutex and shared netlock.
+    Allows to receive packets while forwarding in parallel.
+  <li>Protect multicast deliver loop for UDP and raw IP sockets with rwlock.
+  <li>Only grab netlock in IGMP and MDL6 timer when necessary.
+  <li>TCP slow timer runs without netlock.
+  <li>Rework rwlock so that a writer will get the lock eventually.
+    Readers cannot share the lock forever.
+    This prevents starvation of the writer.
+  <li>Run interface media ioctl with shared netlock so packets
+    can be processed while running ifconfig(8).
+  <li>btrace(8) can be used to debug reference counting.
+  <li>Use MP safe refcount for interface addresses.
   <li>...
