Subject: net: phylink: Add phylink_mac_link_{up, down} wrapper functions
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=27755ff88c0ecbca46bbba1202766c0ce54a3af2;p=openwrt%2Fstaging%2Fblogic.git

net: phylink: Add phylink_mac_link_{up, down} wrapper functions

This is a cosmetic patch that reduces the clutter in phylink_resolve
around calling the .mac_link_up/.mac_link_down driver callbacks.  In a
further patch this logic will be extended to emit notifications in case
a net device does not exist.
