From: Lendacky, Thomas Date: Thu, 14 May 2015 16:44:03 +0000 (-0500) Subject: amd-xgbe: Add netif_* message support to the driver X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34bf65dfa34369d283582cfff2ec916f62043043;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git amd-xgbe: Add netif_* message support to the driver Add support for the network interface message level settings for determining whether to issue some of the driver messages.
