-----Original Message----- From: Intel-wired-lan [mailto:intel-wired-lan-bounces@lists.osuosl.org] On Behalf Of Donald C Skidmore Sent: Friday, June 19, 2015 9:24 AM To: intel-wired-lan@lists.osuosl.org Subject: [Intel-wired-lan] [net-next PATCH] ixgbe: Remove second instance of lan_id variable This patch removes the redundant lan_id in the phy struct and uses the bus version. Both variables exist and intend to represent the STATUS register LAN_ID field. However, phy.lan_id is not bit shifted so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1. Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional lan_id variable and this should make the code less confusing.
