Subject: ipv6: remove unneeded check to pskb_may_pull in ipip6_rcv
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1ad759d8479b4b28f2a6c874d380066cf987b341;p=deliverable%2Flinux.git

ipv6: remove unneeded check to pskb_may_pull in ipip6_rcv

This is already checked by the caller (tunnel64_rcv) and brings ipip6_rcv
in line with ipip_rcv.
