Subject: net: move and rename netif_notify_peers()
X-Git-Tag: v3.7-rc1~145^2~347
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ee89bab14e857678f83a71ee99e575b0fdbb58d4;p=profile%2Fivi%2Fkernel-x86-ivi.git

net: move and rename netif_notify_peers()

I believe net/core/dev.c is a better place for netif_notify_peers(),
because other net event notify functions also stay in this file.

And rename it to netdev_notify_peers().
