From: Scott Feldman Date: Mon, 1 Jun 2015 18:39:02 +0000 (-0700) Subject: rocker: zero allocate ports array X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=27b808cbc2ad72608fb2fd9abd81930d32464546;p=linux-beck.git rocker: zero allocate ports array When allocating the array of rocker port pointers, zero the array values so we can test for !NULL to see if port is allocated/registered. We'll need this later when installing untagged VLAN support for each port, during port probe. It's a long story, but to install a VLAN (vid=0 for untagged, in this case) on a port, we'll need to scan other ports to see if the VLAN group for that VLAN has been setup. To scan the other ports, we need to walk the port array. Signed-off-by: Scott Feldman Signed-off-by: David S.
