From: Karicheri, Muralidharan Date: Mon, 27 Apr 2015 18:12:43 +0000 (-0400) Subject: net: netcp: remove call to netif_carrier_(on/off) for MAC to Phy interface X-Git-Tag: firefly_0821_release~176^2~1829^2~26 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8e046d68ba719a5bb95912c154c6314472edccfa;p=firefly-linux-kernel-4.4.55.git net: netcp: remove call to netif_carrier_(on/off) for MAC to Phy interface Currently when interface type is MAC to Phy, netif_carrier_(on/off) is called which is not needed as Phy lib already updates the carrier status to net stack. This is needed only for other interface types Signed-off-by: Murali Karicheri Signed-off-by: David S.
