Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Fix handling of interrupt status in stmmac driver. Just because we
have masked the event from generating interrupts, doesn't mean the
bit won't still be set in the interrupt status register. From Alexey
Brodkin.
2) Fix DMA API debugging splats in gianfar driver, from Arseny Solokha.
3) Fix off-by-one error in __ip6_append_data(), from Vlad Yasevich.
4) cls_flow does not match on icmpv6 codes properly, from Simon Horman.
5) Initial MAC address can be set incorrectly in some scenerios, from
Ivan Vecera.
6) Packet header pointer arithmetic fix in ip6_tnl_parse_tlv_end_lim(),
from Dan Carpenter.
7) Fix divide by zero in __tcp_select_window(), from Eric Dumazet.
8) Fix crash in iwlwifi when unregistering thermal zone, from Jens
Axboe.
9) Check for DMA mapping errors in starfire driver, from Alexey
Khoroshilov.
