Same problem here.  CONFIG_NET_SCH_FIFO was enabled, apparently by
net/mac80211/Kconfig, but CONFIG_NET_SCHED.  Selecting the later (but none of
the schedulers) fixed the compile error.

However, the is something weird with the new kernel.  DNS has stopped working. 
Under the new kernel, DNS requests get "port unreachable" ICMP responses seen
in Wireshark (sorry, I would have to reboot to get the exact message).  The DNS
server is in a different subnet.  I can ping it and even telnet (over TCP) to
the DNS port 53.

Under the old kernel, the DNS requests are answered properly.

There is no way netdev folks can be unaware of it, so it's just a word of
caution, not a bugreport.
