Subject: cxgbi: fix uninitialized flowi6
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3d6d30d60abb19ba9a20e53ce65b18a9c148fcd1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

cxgbi: fix uninitialized flowi6

ip6_route_output looks into different fields in the passed flowi6 structure,
yet cxgbi passes garbage in nearly all those fields. Zero the structure out
first.

Fixes: fc8d0590d9142 ("libcxgbi: Add ipv6 api to driver")
