Bufferbloat
I backported two big pieces of the solution to bufferbloat:
Byte Queue Limits (BQL) allows network drivers to reduce unnecessary
buffering in their hardware transmit queues. This has been implemented
in the bnx2, bnx2x, e1000e, forcedeth, igb, ixgbe, sfc, skge and tg3
drivers in Linux 3.3 onwards. Documentation is in the commit that added
it, but you're unlikely to need it.
The CoDel queue management algorithm can reduce unnecessary buffering in
software transmit queues. FQ CoDel adds an element of 'fairness' between
multiple network flows. These were implemented as the queue disciplines
codel and fq_codel in Linux 3.5. They can be selected using the tc
command, e.g.: tc qdisc replace dev eth0 root fq_codel

I added BQL support to e1000 but was merged for 3.7, hopefully that
could be backported too...
