Subject: [BRIDGE]: br_dump_ifinfo index fix
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=69ee20a58fa0cad6520c2a9538100a87ef0abd7d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[BRIDGE]: br_dump_ifinfo index fix

Fix for inability of br_dump_ifinfo to handle non-zero start index:
loop index never increases when entered with non-zero start.
Spotted by Kirill Korotaev.
