Subject: [IPV4] ipconfig: fix RARP ic_servaddr breakage
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=82571026b9771c4035b0c62abbbe588fe73373ea;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[IPV4] ipconfig: fix RARP ic_servaddr breakage

memcpy 4 bytes to address of auto unsigned long variable followed
by comparison with u32 is a bloody bad idea.
