From 3c5c9e096b83d53b050bc3ecf98673d00435b039 Mon Sep 17 00:00:00 2001 From: Beilei Xing Date: Thu, 23 Jun 2016 15:22:32 +0800 Subject: [PATCH] net/ixgbe/base: use 8 bits for PCI functions Since PCIe standard defines maximum of 8 functions per device lan_id is a value 0..7. Because of that, lan_id don't need to be u16.
