Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Conflicts:

	drivers/net/wireless/iwlwifi/iwl-agn-rx.c
	drivers/net/wireless/iwlwifi/iwl-trans-pcie-rx.c
	drivers/net/wireless/iwlwifi/iwl-trans.h

Resolved the iwlwifi conflict with mainline using 3-way diff posted
by John Linville and Stephen Rothwell.  In 'net' we added a bug
fix to make iwlwifi report a more accurate skb->truesize but this
conflicted with RX path changes that happened meanwhile in net-next.

In e1000e a conflict arose in the validation code for settings of
adapter->itr.  'net-next' had more sophisticated logic so that
logic was used.
