Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
"Just a bunch of small fixes and tidy ups:
1) Finish the "busy_poll" renames, from Eliezer Tamir.
2) Fix RCU stalls in IFB driver, from Ding Tianhong.
3) Linearize buffers properly in tun/macvtap zerocopy code.
4) Don't crash on rmmod in vxlan, from Pravin B Shelar.
5) Spinlock used before init in alx driver, from Maarten Lankhorst.
6) A sparse warning fix in bnx2x broke TSO checksums, fix from Dmitry
Kravkov.
7) Dummy and ifb driver load failure paths can oops, fixes from Tan
Xiaojun and Ding Tianhong.
8) Correct MTU calculations in IP tunnels, from Alexander Duyck.
9) Account all TCP retransmits in SNMP stats properly, from Yuchung
Cheng.
10) atl1e and via-rhine do not handle DMA mapping failures properly,
from Neil Horman.
11) Various equal-cost multipath route fixes in ipv6 from Hannes
Frederic Sowa"
