Subject: [NETFILTER]: arp_tables: remove obsolete standard_check function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=03dafbbdf8a5e8a9e3e347a393930ed49506d00b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[NETFILTER]: arp_tables: remove obsolete standard_check function

The size check is already performed by xt_check_target, no need
to do it again.
