From: Linus Lüssing Date: Mon, 22 Mar 2010 21:46:14 +0000 (+0100) Subject: Staging: batman-adv: Fix VIS output bug for secondary interfaces X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6497e38fda6970819daacb67725d67474079381;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git Staging: batman-adv: Fix VIS output bug for secondary interfaces TQ and HNA records for originators on secondary interfaces were wrongly being included on the primary interface. Ensure we output a line for each source interface on every node, so we correctly separate primary and secondary interface records.
