Subject: ip_vti: remove the useless err_count check in vti_xmit
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=db32919005d81a375093936a1f625f2d08c2d299;p=openwrt%2Fstaging%2Fblogic.git

ip_vti: remove the useless err_count check in vti_xmit

Unlike ipip and gre, ip_vti never uses err_count in vti4_err,
so no need to check err_count in vti_xmit, it's value always 0.
