Subject: ipv4: fib: Remove unnecessary encap_type check
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=77e12dba07d08080e5124cd9320577f2832a9eab;p=thirdparty%2Fkernel%2Flinux.git

ipv4: fib: Remove unnecessary encap_type check

lwtunnel_build_state() has check validity of encap_type,
so no need to do this before call it.
