Subject: [PATCH] Set diffserv values to AF42 + ECT

AF42 has both the properties of CS42 and the IMM bit.

Whether this has the advantages or disadvantages of just one or
the other, I don't know. With most mac80211 stacks this will
force mosh packets in the VI queue on wireless.

As for pfifo_fast, have to look it up...
