Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Off by one and bounds checking fixes in NFC, from Dan Carpenter.
2) There have been many weird regressions in r8169 since we turned ASPM
support on, some are still not understood nor completely resolved.
Let's turn this back off for now. From Heiner Kallweit.
3) Signess fixes for ethtool speed value handling, from Michael
Zhivich.
4) Handle timestamps properly in macb driver, from Paul Thomas.
5) Two erspan fixes, it's the usual "skb ->data potentially reallocated
and we're holding a stale protocol header pointer". From Lorenzo
Bianconi.
